Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2017-17081)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the gmc_mmx function in libavcodec/x86/mpegvideodsp.c due to improper validation of widths and heights. A remote attacker can supply specially crafted MPEG file, trigger integer signedness error and out-of-array read to cause the service to crash.
