CVE-2023-47466:
Linux Debian vulnerability analysis and mitigation
Overview
CVE-2023-47466 affects TagLib before version 2.0. The vulnerability allows a segmentation violation and application crash during tag writing via a crafted WAV file in which an id3 chunk is the only valid chunk (NVD).
Technical details
The vulnerability occurs when processing WAV files with specially crafted headers where the id3 chunk is the only valid chunk. When attempting to write tags, the existing id3 chunk is removed, leading to a vector::front() call on an empty chunks vector, resulting in a segmentation fault. The vulnerability has been assigned a CVSS v3.1 Base Score of 2.9 LOW with vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L and is classified as a NULL Pointer Dereference (CWE-476) (NVD).
Impact
The vulnerability affects the availability of software systems using the TagLib library. When exploited, it can cause application crashes during tag writing operations. VLC Media player has been confirmed to be affected by this vulnerability (GitHub Issue).
Mitigation and workarounds
The vulnerability has been fixed in TagLib version 2.0. Users should upgrade to this version to mitigate the issue. The fix involves adding a check for empty vectors before calling vector::front() in the updateGlobalSize() function (GitHub Commit).
