Amazon Linux 2 Security Advisory: ALAS2-2026-3141
Advisory Released Date: 2026-02-05
Advisory Updated Date: 2026-02-05
Severity:
Important
Issue Overview:
A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk. (CVE-2026-0719)
