Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2014-7937)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple off-by-one errors in libavcodec/vorbisdec.c in FFmpeg before 2.4.2, as used in Google Chrome before 40.0.2214.91, allow remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted Vorbis I data.


2) Buffer overflow (CVE-ID: CVE-2014-8542)

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.
