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.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
