CVE-2026-81692 (opens in a new tab)How to fix?
Upgrade openssl-encrypt to version 1.4.9 or higher.
Overview
openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the decrypt process when handling FLAC files with a crafted STREAMINFO total_samples field. An attacker can cause excessive memory allocation and exhaust system resources by supplying a small FLAC file that declares an extremely large number of samples.
