Amazon Linux 2 Security Advisory: ALAS-2023-1998
Advisory Release Date: 2023-03-17 16:34 Pacific
Advisory Updated Date: 2023-03-21 23:25 Pacific
Severity:
Medium
Issue Overview:
An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws. (CVE-2021-4156)
