Off-by-one error in the process_cgivars function in contrib/daemonchk.c in Nagios Core 3.5.1, 4.0.2, and earlier allows remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list, which triggers a heap-based buffer over-read.

nagios: denial of service due to off-by-one flaw in process_cgivars()

Multiple off-by-one errors in Nagios Core 3.5.1, 4.0.2, and earlier, and Icinga before 1.8.5, 1.9 before 1.9.4, and 1.10 before 1.10.2 allow remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list to the process_cgivars function in (1) avail.c, (2) cmd.c, (3) config.c, (4) extinfo.c, (5) histogram.c, (6) notifications.c, (7) outages.c, (8) status.c, (9) statusmap.c, (10) summary.c, and (11) trends.c in cgi/, which triggers a heap-based buffer over-read.

Multiple integer overflows in the Microsoft (1) JScript 5.6 through 5.8 and (2) VBScript 5.6 through 5.8 scripting engines allow remote attackers to execute arbitrary code via a crafted web page, aka "Scripting Memory Reallocation Vulnerability."

libpng: application crash or possible arbitrary code execution in libpng 1.5.0

pngrtran.c in libpng 1.5.x before 1.5.1 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted palette-based PNG image that triggers a buffer overflow, related to the png_do_expand_palette function, the png_do_rgb_to_gray function, and an integer underflow. NOTE: some of these details are obtained from third party information.

qffmpeg: integer overflow and out of array accesses in libavcodec/dsputil.c

Multiple integer signedness errors in libavcodec/dsputil.c in FFmpeg before 2.1 allow remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted data.

Integer overflow in QuickTime in Apple Mac OS X before 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file.

Integer overflow in QuickTime in Apple Mac OS X before 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted RIFF WAV file.

pidgin: Heap-based buffer overflow in SIMPLE protocol plugin

The SIMPLE protocol functionality in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a negative Content-Length header, which triggers a buffer overflow.

Mozilla integer overflow in frameset spec (MFSA 2011-12)

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.19 and 3.6.x before 3.6.17, Thunderbird before 3.1.10, and SeaMonkey before 2.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors, a different vulnerability than CVE-2011-0072, CVE-2011-0074, CVE-2011-0075, and CVE-2011-0078.

pidgin: Heap-based buffer overflow in MXit emoticon parsing

Integer signedness error in the MXit functionality in Pidgin before 2.10.8 allows remote attackers to cause a denial of service (segmentation fault) via a crafted emoticon value, which triggers an integer overflow and a buffer overflow.

libFS: Sign extension issues resulting in heap-based buffer overflow

X.org libFS 1.0.4 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to an unexpected sign extension in the FSOpenServer function.

CCID: Integer overflow, leading to array index error when processing crafted serial number of certain cards

Signedness error in ccid_serial.c in libccid in the USB Chip/Smart Card Interface Devices (CCID) driver, as used in pcscd in PCSC-Lite 1.5.3 and possibly other products, allows physically proximate attackers to execute arbitrary code via a smart card with a crafted serial number that causes a negative value to be used in a memcpy operation, which triggers a buffer overflow. NOTE: some sources refer to this issue as an integer overflow.

pidgin: Heap-based buffer overflow when parsing chunked HTTP responses

Buffer overflow in util.c in libpurple in Pidgin before 2.10.8 allows remote HTTP servers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid chunk-size field in chunked transfer-coding data.

Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel before 2.6.37 on platforms other than x86 allows local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.

pidgin: DoS via specially-crafted stun messages

The STUN protocol implementation in libpurple in Pidgin before 2.10.8 allows remote STUN servers to cause a denial of service (out-of-bounds write operation and application crash) by triggering a socket read error.

kernel: integer overflow in ext4_ext_get_blocks()

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation.

Integer overflow in Google Chrome before 9.0.597.107 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors involving a TEXTAREA element.
