Description
This security bulletin contains information about 6 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2014-8542)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
libavcodec/utils.c in FFmpeg before 2.4.2 omits a certain codec ID during enforcement of alignment, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted JV data.
2) Input validation error (CVE-ID: CVE-2014-8543)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
libavcodec/mmvideo.c in FFmpeg before 2.4.2 does not consider all lines of HHV Intra blocks during validation of image height, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MM video data.
3) Input validation error (CVE-ID: CVE-2014-8544)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
libavcodec/tiff.c in FFmpeg before 2.4.2 does not properly validate bits-per-pixel fields, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted TIFF data.
4) Buffer overflow (CVE-ID: CVE-2014-8547)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
libavcodec/gifdec.c in FFmpeg before 2.4.2 does not properly compute image heights, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted GIF data.
5) Buffer overflow (CVE-ID: CVE-2014-8548)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Off-by-one error in libavcodec/smc.c in FFmpeg before 2.4.2 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Quicktime Graphics (aka SMC) video data.
6) Input validation error (CVE-ID: CVE-2014-9604)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
libavcodec/utvideodec.c in FFmpeg before 2.5.2 does not check for a zero value of a slice height, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Ut Video data, related to the (1) restore_median and (2) restore_median_il functions.
