CVE-2023-47212

CVSS v2.0

10

Critical

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions stb vorbis.c version 1.22
Description A heap-based buffer overflow vulnerability exists in the comment functionality of stb vorbis.c. A specially crafted .ogg file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability, potentially allowing for code execution. The root cause is a potential integer overflow in sizeof(char*) * (f->comment list length), which may cause setup malloc to allocate less memory than required.
Recommendations As a temporary workaround, consider disabling the start decoder function until a patch is available. Restrict access to the comment functionality in stb vorbis.c to minimize the risk of exploitation. Avoid using specially crafted .ogg files with stb vorbis.c until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
