GentooCVEs & Vulnerabilities

ViewVC before 1.0.5 provides revision metadata without properly checking whether access was intended, which allows remote attackers to obtain sensitive information by reading (1) forbidden pathnames in the revision view, (2) log history that can only be reached by traversing a forbidden object, or (3) forbidden diff view path parameters.

The docert function in ssl-cert.eclass, when used by src_compile or src_install on Gentoo Linux, stores the SSL key in a binpkg, which allows local users to extract the key from the binpkg, and causes multiple systems that use this binpkg to have the same SSL key and certificate.

expn in the am-utils and net-fs packages for Gentoo, rPath Linux, and other distributions, allows local users to overwrite arbitrary files via a symlink attack on the expn[PID] temporary file. NOTE: this is the same issue as CVE-2003-0308.1.

Xdg-utils 1.0.2 and earlier allows user-assisted remote attackers to execute arbitrary commands via shell metacharacters in a URL argument to (1) xdg-open or (2) xdg-email.

Unspecified vulnerability in the bzip2 decompression algorithm in nsis/bzlib_private.h in ClamAV before 0.92 has unknown impact and remote attack vectors.

etc-update in Portage before 2.1.3.11 on Gentoo Linux relies on the umask to set permissions for the merge file, often resulting in permissions weaker than those of the original files, which might allow local users to obtain sensitive information by reading the merge file.

The Gentoo ebuild of MLDonkey before 2.9.0-r3 has a p2p user account with an empty default password and valid login shell, which might allow remote attackers to obtain login access and execute arbitrary code.

Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.

NVIDIA drivers (nvidia-drivers) before 1.0.7185, 1.0.9639, and 100.14.11, as used in Gentoo Linux and possibly other distributions, creates /dev/nvidia* device files with insecure permissions, which allows local users to modify video card settings, cause a denial of service (crash or physical video card damage), and obtain sensitive information.

Vixie Cron before 4.1-r10 on Gentoo Linux is installed with insecure permissions, which allows local users to cause a denial of service (cron failure) by creating hard links, which results in a failed st_nlink check in database.c.

The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.

The Linux Security Auditing Tool (LSAT) allows local users to overwrite arbitrary files via a symlink attack on temporary files, as demonstrated using /tmp/lsat1.lsat.

ftpd, as used by Gentoo and Debian Linux, sets the gid to the effective uid instead of the effective group id before executing /bin/ls, which allows remote authenticated users to list arbitrary directories with the privileges of gid 0 and possibly enable additional attack vectors.

Cross-site scripting (XSS) vulnerability in the wp_explain_nonce function in the nonce AYS functionality (wp-includes/functions.php) for WordPress 2.0 before 2.0.9 and 2.1 before 2.1.1 allows remote attackers to inject arbitrary web script or HTML via the file parameter to wp-admin/templates.php, and possibly other vectors involving the action variable.

The gencert.sh script, when installing OpenLDAP before 2.1.30-r10, 2.2.x before 2.2.28-r7, and 2.3.x before 2.3.30-r2 as an ebuild in Gentoo Linux, does not create temporary directories in /tmp securely during emerge, which allows local users to overwrite arbitrary files via a symlink attack.

The JPEG library in media-libs/jpeg before 6b-r7 on Gentoo Linux is built without the -maxmem feature, which could allow context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted JPEG file that exceeds the intended memory limits.

The configuration of NetHack 3.4.3-r1 and earlier, Falcon's Eye 1.9.4a and earlier, and Slash'EM 0.0.760 and earlier on Gentoo Linux allows local users in the games group to modify saved games files to execute arbitrary code via buffer overflows and overwrite arbitrary files via symlink attacks.

The ebuild for pinentry before 0.7.2-r2 on Gentoo Linux sets setgid bits for pinentry programs, which allows local users to read or overwrite arbitrary files as gid 0.

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.

Second-order symlink vulnerability in eix-sync.in in Ebuild IndeX (eix) before 0.5.0_pre2 allows local users to overwrite arbitrary files via a symlink attack on the exi.X.sync temporary file, which is processed by the diff-eix program.

Cross-site scripting (XSS) vulnerability in view_all_set.php in Mantis 0.19.0a1 through 1.0.0a3 allows remote attackers to inject arbitrary web script or HTML via the dir parameter, as identified by bug#0005959, and a different vulnerability than CVE-2005-3090.

The bgp_update_print function in tcpdump 3.x does not properly handle a -1 return value from the decode_prefix4 function, which allows remote attackers to cause a denial of service (infinite loop) via a crafted BGP packet.

The fn_show_postinst function in Gentoo webapp-config before 1.10-r14 allows local users to overwrite arbitrary files via a symlink attack on the postinst.txt temporary file.

poppassd_pam 1.0 and earlier, when changing a user password, does not verify that the user entered the old password correctly, which allows remote attackers to change passwords for arbitrary users.

Heap-based buffer overflow in psd.c for ImageMagick 6.1.0, 6.1.7, and possibly earlier versions allows remote attackers to execute arbitrary code via a .PSD image file with a large number of layers.

The DBI library (libdbi-perl) for Perl allows local users to overwrite arbitrary files via a symlink attack on a temporary PID file.

The ebuild of Webmin before 1.170-r3 on Gentoo Linux includes the encrypted root password in the miniserv.users file when building a tbz2 of the webmin package, which allows remote attackers to obtain and possibly crack the encrypted password.

Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete.

Format string vulnerability in the my_xlog function in lib.c for Oops! Proxy Server 1.5.23 and earlier, as called by the auth functions in the passwd_mysql and passwd_pgsql modules, may allow attackers to execute arbitrary code via a URL.

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.

The (1) check_update.sh and (2) rkhunter script in Rootkit Hunter before 1.2.3-r1 create temporary files with predictable file names, which allows local users to overwrite arbitrary files via a symlink attack.
