Multiple integer overflows in (1) filter/image-png.c and (2) filter/image-zoom.c in CUPS 1.3 allow attackers to cause a denial of service (crash) and trigger memory corruption, as demonstrated via a crafted PNG image.

Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.

Buffer overflow in rsync 2.6.9 to 3.0.1, with extended attribute (xattr) support enabled, might allow remote attackers to execute arbitrary code via unknown vectors.

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.

The CairoFont::create function in CairoFontEngine.cc in Poppler, possibly before 0.8.0, as used in Xpdf, Evince, ePDFview, KWord, and other applications, does not properly handle embedded fonts in PDF files, which allows remote attackers to execute arbitrary code via a crafted font object, related to dereferencing a function pointer associated with the type of this font object.

Eterm 0.9.4 opens a terminal window on :0 if -display is not specified and the DISPLAY environment variable is not set, which might allow local users to hijack X11 connections. NOTE: realistic attack scenarios require that the victim enters a command on the wrong machine.

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.

The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect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

Array index vulnerability in Speex 1.1.12 and earlier, as used in libfishsound 0.9.0 and earlier, including Illiminable DirectShow Filters and Annodex Plugins for Firefox, xine-lib before 1.1.12, and many other products, allows remote attackers to execute arbitrary code via a header structure containing a negative offset, which is used to dereference a function pointer.

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)

Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2008-0887. Reason: This candidate is a duplicate of CVE-2008-0887. Notes: All CVE users should reference CVE-2008-0887 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage

Multiple integer overflows in imageop.c in Python before 2.5.3 allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted images that trigger heap-based buffer overflows. NOTE: this issue is due to an incomplete fix for CVE-2007-4965.

Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm.

The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x before 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory.

The asn1 implementation in (a) the Linux kernel 2.4 before 2.4.36.6 and 2.6 before 2.6.25.5, as used in the cifs and ip_nat_snmp_basic modules; and (b) the gxsnmp package; does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding.

OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference.

start_kdeinit in KDE 3.5.5 through 3.5.9, when installed setuid root, allows local users to cause a denial of service and possibly execute arbitrary code via "user-influenceable input" (probably command-line arguments) that cause start_kdeinit to send SIGUSR1 signals to other processes.

Heap-based buffer overflow in the progressive PNG Image loader (decoders/pngloader.cpp) in KHTML in KDE 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted image.

Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain "re-ordered access to the descriptor table."

Format string vulnerability in the grant helper (polkit-grant-helper.c) in PolicyKit 0.7 and earlier allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via format strings in a password.
