CVE-2021-4156

Description

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.

Priority: MEDIUM
CVSS v3: 8.1
Component: libsndfile1
Publish Date: Dec 23, 2021
Related ID: --
CVSS v2: HIGH
