Bug 874876 – <net-misc/openssh-9.1_p1: multiple minor memory safety issues

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Agostino Sarubbo 2022-10-04 11:19:21 UTC]

From https://www.openwall.com/lists/oss-security/2022/10/04/1 :

Security
========

This release contains fixes for three minor memory safety problems.
None are believed to be exploitable, but we report most memory safety
problems as potential security vulnerabilities out of caution.

 * ssh-keyscan(1): fix a one-byte overflow in SSH- banner processing.
   Reported by Qualys

 * ssh-keygen(1): double free() in error path of file hashing step in
   signing/verify code; GHPR333

 * ssh-keysign(8): double-free in error path introduced in openssh-8.9
