The (1) psp (aka .tub), (2) bmp, (3) pcx, and (4) psd plugins in gimp allow user-assisted remote attackers to cause a denial of service (crash or memory consumption) via crafted image files, as discovered using the fusil fuzzing tool.
Directory traversal vulnerability in the contains_dot_dot function in src/names.c in GNU tar allows user-assisted remote attackers to overwrite arbitrary files via certain //.. (slash slash dot dot) sequences in directory symlinks in a TAR archive.
Emacs 21 allows user-assisted attackers to cause a denial of service (crash) via certain crafted images, as demonstrated via a GIF image in vm mode, related to image size calculation.
GNU screen 4.0.3 allows local users to unlock the screen via a CTRL-C sequence at the password prompt. NOTE: multiple third parties report inability to reproduce this issue
Heap-based buffer overflow in the visit_old_format function in locate/locate.c in locate in GNU findutils before 4.2.31 might allow context-dependent attackers to execute arbitrary code via a long pathname in a locate database that has the old format, a different vulnerability than CVE-2001-1036.
Cross-site scripting (XSS) vulnerability in gnatsweb.pl in Gnatsweb 4.00 and Gnats 4.1.99 allows remote attackers to inject arbitrary web script or HTML via the database parameter.
server/parser/sprite_definition.cpp in GNU Gnash (aka GNU Flash Player) 0.7.2 allows remote attackers to execute arbitrary code via a large number of SHOWFRAME elements within a DEFINESPRITE element, which triggers memory corruption and enables the attacker to call free with an arbitrary address, probably resultant from a buffer overflow.
(1) Mozilla Firefox 2.0.0.3 and (2) GNU IceWeasel 2.0.0.3 allow remote attackers to cause a denial of service (browser crash or system hang) via JavaScript that matches a regular expression against a long string, as demonstrated using /(.)*/.
Untrusted search path vulnerability in the libtool-ltdl library (libltdl.so) 1.5.22-2.3 in Fedora Core 5 might allow local users to execute arbitrary code via a malicious library in the (1) hwcap, (2) 0, and (3) nosegneg subdirectories.
GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection.
