Amazon Linux 2023 Security Advisory: ALAS2023-2026-2047
Advisory Released Date: 2026-08-17
Advisory Updated Date: 2026-08-17
Severity:
Important
Issue Overview:
GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior. (CVE-2026-58469)
Affected Packages:
wget
Issue Correction:
Run dnf update wget --releasever 2023.12.20260817 or dnf update --advisory ALAS2023-2026-2047 --releasever 2023.12.20260817 to update your system.
