Directory traversal vulnerability in the -x (extract) command line option in unarj allows remote attackers to overwrite arbitrary files via an arj archive with filenames that contain .. (dot dot) sequences.

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.

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 does not allow extensions to prevent password changes without using both Special:PasswordReset and Special:ChangePassword, which allows remote attackers to bypass the intended restrictions of an extension that only implements one of these blocks.

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.

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.

mirrorselect before 0.89 creates temporary files in a world-writable location with predictable file names, which allows remote attackers to overwrite arbitrary files via a symlink attack.
