Description

Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free.

Affected configurations

• openbsd openssh (<= 4.4) • debian debian linux 3.1 • apple mac os x (< 10.3.9) • apple mac os x (>= 10.4 <= 10.4.8) • apple mac os x server (< 10.3.9) • apple mac os x server (>= 10.4 <= 10.4.8)
