Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2018-13302)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper handling of frame types of multiple independent substreams in the handle_eac3 function in libavformat/movenc.c in EAC3_FRAME_TYPE_INDEPENDENT). A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger out-of-bounds read and cause the service to crash.
