KdeCVEs & Vulnerabilities

Konqueror 3.5.5 allows remote attackers to cause a denial of service (crash) by using JavaScript to read a child iframe having an ftp:// URI.

The FTP protocol implementation in Konqueror 3.5.5 allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.

Kmail 1.9.1 on KDE 3.5.2, with "Prefer HTML to Plain Text" enabled, allows remote attackers to cause a denial of service (crash) via an HTML e-mail with certain table and frameset tags that trigger a segmentation fault, possibly involving invalid free or delete operations.

ecma/kjs_html.cpp in KDE JavaScript (KJS), as used in Konqueror in KDE 3.5.5, allows remote attackers to cause a denial of service (crash) by accessing the content of an iframe with an ftp:// URI in the src attribute, probably due to a NULL pointer dereference.

KMail 1.9.5 and earlier does not properly use the --status-fd argument when invoking GnuPG, which prevents KMail from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows remote attackers to forge the contents of a message without detection.

The KDE HTML library (kdelibs), as used by Konqueror 3.5.5, does not properly parse HTML comments, which allows remote attackers to conduct cross-site scripting (XSS) attacks and bypass some XSS protection schemes by embedding certain HTML tags within a comment in a title tag, a related issue to CVE-2007-0478.

The Adobe PDF specification 1.3, as implemented by (a) xpdf 3.0.1 patch 2, (b) kpdf in KDE before 3.5.5, (c) poppler before 0.5.4, and other products, allows remote attackers to have an unknown impact, possibly including denial of service (infinite loop), arbitrary code execution, or memory corruption, via a PDF file with a (1) crafted catalog dictionary or (2) a crafted Pages attribute that references an invalid page tree node.

KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference. NOTE: this issue was originally reported as a buffer overflow.

The nodeType function in KDE libkhtml 4.2.0 and earlier, as used by Konquerer, KMail, and other programs, allows remote attackers to cause a denial of service (crash) via malformed HTML tags, possibly involving a COL SPAN tag embedded in a RANGE tag.

Stack consumption vulnerability in the KFILE JPEG (kfile_jpeg) plugin in kdegraphics 3, as used by konqueror, digikam, and other KDE image browsers, allows remote attackers to cause a denial of service (stack consumption) via a crafted EXIF section in a JPEG file, which results in an infinite recursion.

kdesktop_lock in kdebase before 3.1.3-5.11 for KDE in Red Hat Enterprise Linux (RHEL) 3 does not properly terminate, which can prevent the screensaver from activating or prevent users from manually locking the desktop.

KDE Konqueror 3.5.1 and earlier allows remote attackers to cause a denial of service (application crash) by calling the replaceChild method on a DOM object, which triggers a null dereference, as demonstrated by calling document.replaceChild with a 0 (zero) argument.

KDE Display Manager (KDM) in KDE 3.2.0 up to 3.5.3 allows local users to read arbitrary files via a symlink attack related to the session type for login.

artswrapper in aRts, when running setuid root on Linux 2.6.0 or later versions, does not check the return value of the setuid function call, which allows local users to gain root privileges by causing setuid to fail, which prevents artsd from dropping privileges.

Heap-based buffer overflow in the encodeURI and decodeURI functions in the kjs JavaScript interpreter engine in KDE 3.2.0 through 3.5.0 allows remote attackers to execute arbitrary code via a crafted, UTF-8 encoded URI.

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

Konqueror can associate a cookie with multiple domains when the DNS resolver has a non-root domain in its search list, which allows remote attackers to trick a user into accepting a cookie for a hostname formed via search-list expansion of the hostname entered by the user, or steal a cookie for an expanded hostname, as demonstrated by an attacker who operates an ap1.com Internet web site to steal cookies associated with an ap1.com.example.com intranet web site.

langen2kvtml in KDE 3.0 to 3.4.2 creates insecure temporary files in /tmp with predictable names, which allows local users to overwrite arbitrary files.

xpdf and kpdf do not properly validate the "loca" table in PDF files, which allows local users to cause a denial of service (disk consumption and hang) via a PDF file with a "broken" loca table, which causes a large temporary file to be created when xpdf attempts to reconstruct the information.

Multiple integer overflows in libgadu, as used in Kopete in KDE 3.2.3 to 3.4.1, ekg before 1.6rc3, GNU Gadu, CenterICQ, Kadu, and other packages, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an incoming message.

The (1) Kate and (2) Kwrite applications in KDE KDE 3.2.x through 3.4.0 do not properly set the same permissions on the backup file as were set on the original file, which could allow local users and possibly remote attackers to obtain sensitive information.

Multiple vulnerabilities in fliccd, when installed setuid root as part of the kdeedu Kstars support for Instrument Neutral Distributed Interface (INDI) in KDE 3.3 to 3.3.2, allow local users and remote attackers to execute arbitrary code via stack-based buffer overflows.

The KDE screen saver in KDE before 3.0.5 does not properly check the return value from a certain function call, which allows attackers with physical access to cause a crash and access the desktop session.

KPPP 2.1.2 in KDE 3.1.5 and earlier, when setuid root without certain wrappers, does not properly close a privileged file descriptor for a domain socket, which allows local users to read and write to /etc/hosts and /etc/resolv.conf and gain control over DNS name resolution by opening a number of file descriptors before executing kppp.

The International Domain Name (IDN) support in Konqueror 3.2.1 on KDE 3.2.1 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.

The dcopidlng script in KDE 3.2.x and 3.3.x creates temporary files with predictable filenames, which allows local users to overwrite arbitrary files via a symlink attack.

Desktop Communication Protocol (DCOP) daemon, aka dcopserver, in KDE before 3.4 allows local users to cause a denial of service (dcopserver consumption) by "stalling the DCOP authentication process."

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Kommander in KDE 3.2 through KDE 3.4.0 executes data files without confirmation from the user, which allows remote attackers to execute arbitrary code.

Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.

Multiple integer overflows in xpdf 2.0 and 3.0, and other packages that use xpdf code such as CUPS, gpdf, and kdegraphics, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0889.

Multiple integer overflows in xpdf 3.0, and other packages that use xpdf code such as CUPS, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0888.

Buffer overflow in the Gfx::doImage function in Gfx.cc for xpdf 3.00, and other products that share code such as tetex-bin and kpdf in KDE 3.2.x to 3.2.3 and 3.3.x to 3.3.2, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted PDF file that causes the boundaries of a maskColors array to be exceeded.

Konqueror 3.x up to 3.2.2-6, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window or tab whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.

KDE 3.2.x and 3.3.0 through 3.3.2, when saving credentials that are (1) manually entered by the user or (2) created by the SMB protocol handler, stores those credentials for plaintext in the user's .desktop file, which may be created with world-readable permissions, which could allow local users to obtain usernames and passwords for remote resources such as SMB shares.

Konqueror 3.3.1 allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline ("%0a") before the FTP command, which causes the commands to be inserted into the resulting FTP session, as demonstrated using a PORT command.

Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files.

Mozilla Firefox 0.9.2 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session. NOTE: it was later reported that 2.x is also affected.

Konqueror in KDE 3.2.3 and earlier allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk and .firm.in, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session.
