Description

This security bulletin contains information about 1 security vulnerability.


1) Buffer overflow (CVE-ID: CVE-2017-14767)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c in FFmpeg before 3.3.4 mishandles empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer overflow) or possibly have unspecified other impact via a crafted sdp file.
