Stack-based buffer overflow in SMGSHR.EXE in OpenVMS for Integrity Servers 8.2-1, 8.3, and 8.3-1H1 and OpenVMS ALPHA 7.3-2, 8.2, and 8.3 allows local users to cause a denial of service (crash) or gain privileges via unspecified vectors.
The default configuration of the POP server in TCP/IP Services 5.6 for HP OpenVMS 8.3 generates different responses depending on whether or not a username is valid, which allows remote attackers to enumerate valid POP usernames.
The default configuration of the POP server in TCP/IP Services 5.6 for HP OpenVMS 8.3 does not log the source IP address or attempted username for login attempts, which might help remote attackers to avoid identification.
The Pascal run-time library (PAS$RTL.EXE) before 20070418 on OpenVMS for Integrity Servers 8.3, and PAS$RTL.EXE before 20070419 on OpenVMS Alpha 8.3, does not properly restore PC and PSL values, which allows local users to cause a denial of service (system crash) via certain Pascal code.
Unspecified vulnerability in HP OpenVMS for Integrity Servers 8.2-1 and 8.3 allows local users to cause a denial of service (crash) via "Program actions relating to exceptions."
