SubversionCVEs & Vulnerabilities

Multiple integer overflows in the libsvn_delta library in Subversion before 1.5.7, and 1.6.x before 1.6.4, allow remote authenticated users and remote Subversion servers to execute arbitrary code via an svndiff stream with large windows that trigger a heap-based buffer overflow, a related issue to CVE-2009-2412.

Directory traversal vulnerability in Subversion before 1.4.5, as used by TortoiseSVN before 1.4.5 and possibly other products, when run on Windows-based systems, allows remote authenticated users to overwrite and create arbitrary files via a ..\ (dot dot backslash) sequence in the filename, as stored in the file repository.

Subversion 1.4.3 and earlier does not properly implement the "partial access" privilege for users who have access to changed paths but not copied paths, which allows remote authenticated users to obtain sensitive information (revision properties) via svn (1) propget, (2) proplist, or (3) propedit.

The mod_authz_svn Apache module for Subversion 1.0.4-r1 and earlier allows remote authenticated users, with write access to the repository, to read unauthorized parts of the repository via the svn copy command.

The mod_authz_svn module in Subversion 1.0.7 and earlier does not properly restrict access to all metadata on unreadable paths, which could allow remote attackers to gain sensitive information via (1) svn log -v, (2) svn propget, or (3) svn blame, and other commands that follow renames.

libsvn_ra_svn in Subversion 1.0.4 trusts the length field of (1) svn://, (2) svn+ssh://, and (3) other svn protocol URL strings, which allows remote attackers to cause a denial of service (memory consumption) and possibly execute arbitrary code via an integer overflow that leads to a heap-based buffer overflow.

Stack-based buffer overflow during the apr_time_t data conversion in Subversion 1.0.2 and earlier allows remote attackers to execute arbitrary code via a (1) DAV2 REPORT query or (2) get-dated-rev svn-protocol command.
