/etc/pam.d/su is wrong in RHEL-4.6

The default configuration of su in /etc/pam.d/su in GNU coreutils 5.2.1 allows local users to gain the privileges of a (1) locked or (2) expired account by entering the account name on the command line, related to improper use of the pam_succeed_if.so module.

emacs insecure /tmp file usage

vcdiff in Emacs 20.7 to 22.1.50, when used with SCCS, allows local users to overwrite arbitrary files via a symlink attack on temporary files.

m4: code execution via -F argument

Unspecified vulnerability in GNU m4 before 1.4.11 might allow context-dependent attackers to execute arbitrary code, related to improper handling of filenames specified with the -F option. NOTE: it is not clear when this issue crosses privilege boundaries.

m4: unquoted output of maketemp and mkstemp

The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect filename.

gcc: gcc-4.2 may optimize out certain length checks

gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about this removal. NOTE: the vendor has determined that this compiler behavior is correct according to section 6.5.6 of the C99 standard (aka ISO/IEC 9899:1999)

Kernel doesn't clear DF for signal handlers

gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation such as memcpy and memmove on x86 and i386, which can prevent the direction flag (DF) from being reset in violation of ABI conventions and cause data to be copied in the wrong direction during signal handling in the Linux kernel, which might allow context-dependent attackers to trigger memory corruption. NOTE: this issue was originally reported for CPU consumption in SBCL.

libcdio: long Joliet file name buffer overflow

Stack-based buffer overflow in the print_iso9660_recurse function in iso-info (src/iso-info.c) in GNU Compact Disc Input and Control Library (libcdio) 0.79 and earlier allows context-dependent attackers to cause a denial of service (core dump) and possibly execute arbitrary code via a disk or image that contains a long joilet file name.

gnump3d 2.9final does not apply password protection to its plugins, which might allow remote attackers to bypass intended access restrictions.

Emacs buffer overflows

Stack-based buffer overflow in emacs allows user-assisted attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a large precision value in an integer format string specifier to the format function, as demonstrated via a certain "emacs -batch -eval" command line.

emacs insufficient safe mode checks

The hack-local-variables function in Emacs before 22.2, when enable-local-variables is set to :safe, does not properly search lists of unsafe or risky variables, which might allow user-assisted attackers to bypass intended restrictions and modify critical program variables via a file containing a Local variables declaration.

emacs tramp unsafe temporary file usage

The (1) tramp-make-temp-file and (2) tramp-make-tramp-temp-file functions in Tramp 2.1.10 extension for Emacs, and possibly earlier 2.1.x versions, allows local users to overwrite arbitrary files via a symlink attack on temporary files.

tar/cpio stack crashing in safer_name_suffix

Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack."

tar directory traversal vulnerability

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.

Gimp image loader multiple input validation flaws

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.

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

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.

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.

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.

(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 /(.)*/.
