Multiple buffer overflows in IBM Tivoli Storage Manager (TSM) before 5.2.9 and 5.3.x before 5.3.4 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in (1) the language field at logon that begins with a 0x18 byte, (2) two unspecified parameters to the SmExecuteWdsfSession function, and (3) the contact field in an open registration message.

Heap-based buffer overflow in adsmdll.dll 5.3.7.7296, as used by the daemon (dsmsvc.exe) in the backup server in IBM Tivoli Storage Manager (TSM) Express 5.3.7.3 and earlier and TSM 5.2, 5.3 before 5.3.6.0, and 5.4.0.0 through 5.4.4.0, allows remote attackers to execute arbitrary code via a crafted length value.

Stack-based buffer overflow in the client acceptor daemon (CAD) scheduler in the client in IBM Tivoli Storage Manager (TSM) 5.3 before 5.3.6.7, 5.4 before 5.4.3, 5.5 before 5.5.2.2, and 6.1 before 6.1.0.2, and TSM Express 5.3.3.0 through 5.3.6.6, allows remote attackers to execute arbitrary code via crafted data in a TCP packet.

Multiple unspecified vulnerabilities in the (1) UNIX and (2) Linux backup-archive clients, and the (3) OS/400 API client, in IBM Tivoli Storage Manager (TSM) 5.3 before 5.3.6.6, 5.4 before 5.4.2, and 5.5 before 5.5.1, when the MAILPROG option is enabled, allow attackers to read, modify, or delete arbitrary files via unknown vectors.

Buffer overflow in the traditional client scheduler in the client in IBM Tivoli Storage Manager (TSM) 5.3 before 5.3.6.7 and 5.4 before 5.4.2 allows remote attackers to execute arbitrary code via unspecified vectors.
