Amazon Linux 2 Security Advisory: ALAS2-2025-3094
Advisory Released Date: 2025-12-08
Advisory Updated Date: 2025-12-08
Severity:
Important
Issue Overview:
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string. (CVE-2025-13601)
