The IBM Tivoli Storage Manager (IBM Spectrum Protect) AIX client is vulnerable to a buffer overflow when Journal-Based Backup is enabled. A local attacker could overflow a buffer and execute arbitrary code on the system or cause a system crash.
The server in IBM Spectrum Protect (aka Tivoli Storage Manager) 5.5 and 6.x before 6.3.5.1 and 7.x before 7.1.4 does not properly restrict use of the ASNODENAME option, which allows remote attackers to read or write to backup data by leveraging proxy authority.
