Name of the Vulnerable Software and Affected Versions
FFmpeg (affected versions not specified)
Description
The issue is related to the
smc encode stream function in the libavcodec/smcenc.c component of the FFmpeg library. It involves an out-of-bounds read due to the manipulation of the y size argument, which can be exploited remotely. This could allow an attacker to access confidential data and cause a denial of service.Recommendations
To fix this issue, it is recommended to apply a patch. The specific patch name is 13c13109759090b7f7182480d075e13b36ed8edd. As a temporary workaround, consider restricting access to the
smc encode stream function until a patch is available. Additionally, avoid manipulating the y size argument in the affected component to minimize the risk of exploitation.Exploit
