EUVDB-ID: #VU29635
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-13904
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in FFmpeg when processing a crafted EXTINF duration in an m3u8 file because parse_playlist in
libavformat/hls.c frees a pointer, and later that pointer is accessed in
av_probe_input_format3 in libavformat/format.c. A remote attacker can trick the victim to open a specially crafted media file or playlist, trigger a use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
