FAQs regarding Amazon Linux ALAS/CVE Severity

Issue Overview:

SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read. (CVE-2025-47914)

SSH servers parsing GSSAPI authentication requests do not validate the number of mechanisms specified in the request, allowing an attacker to cause unbounded memory consumption. (CVE-2025-58181)

Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption. (CVE-2025-61729)

Issue Correction:
Run dnf update docker --releasever 2023.10.20260105 or dnf update --advisory ALAS2023-2025-1340 --releasever 2023.10.20260105 to update your system.
