Description
This security bulletin contains information about 1 vulnerability.
1) Use-after-free (CVE-ID: CVE-2019-14437)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
The xiph_SplitHeaders function in modules/demux/xiph.h in VideoLAN VLC media player 3.0.7.1 does not check array bounds properly. As a result, a heap-based buffer over-read can be triggered via a crafted .ogg file.
