Symantec Messaging Gateway Buffer Overflow

A privilege escalation flaw allows a malicious, authenticated, privileged CLI user to escalate their privileges on the system and gain full control over the SMG appliance. This affects SMG prior to 10.7.4.

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.

An information disclosure flaw allows a malicious, authenticated, privileged web UI user to obtain a password for a remote SCP backup server that they might not otherwise be authorized to access. This affects SMG prior to 10.7.4.

A malicious authenticated SMG administrator user can obtain passwords for external LDAP/Active Directory servers that they might not otherwise be authorized to access.
