Description of the vulnerability

Several vulnerabilities were announced in IBM Tivoli Storage Manager Fastback.

An attacker can send an UDP packet to the Mount service (FastBackMount.exe, 30005/udp), in order to change a byte in memory. [severity:3/4; CVE-2010-3759, ZDI-10-179]

An attacker can send a long log message to the FastBackServer.exe server (11406/tcp), in order to generate an overflow in AGI_SendToLog(). [severity:3/4; CVE-2010-3758, ZDI-10-180]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to generate an overflow in _AGI_S_ActivateLTScriptReply(). [severity:3/4; CVE-2010-3758, ZDI-10-181]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to generate an overflow in FXCLI_OraBR_Exec_Command(). [severity:3/4; CVE-2010-3754, ZDI-10-182]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to generate an overflow in FXCLI_checkIndexDBLocation(). [severity:3/4; CVE-2010-3758, ZDI-10-183]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to generate an overflow in USER_S_AddADGroup(). [severity:3/4; CVE-2010-3758, ZDI-10-184]

An attacker can send a special message to the FastBackServer.exe server (11406/tcp), in order to generate a format string attack in _Eventlog(). [severity:3/4; CVE-2010-3757, ZDI-10-185]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to generate an error in _CalcHashValueWithLength(), which stops the service. [severity:2/4; CVE-2010-3756, ZDI-10-186]

An attacker can send a long message to the FastBackServer.exe server (11406/tcp), in order to dereference a NULL pointer in _DAS_ReadBlockReply(), which stops the service. [severity:2/4; CVE-2010-3755, ZDI-10-187]

An attacker can send a long 0xFAFBFCFD message to the FastBackServer.exe server (1320/tcp), in order to generate a buffer overflow. [severity:3/4; ZDI-10-200]

An attacker can send a malicious packet to the Mount service (FastBackMount.exe, 30051/tcp), in order to dereference a NULL pointer. [severity:1/4; CVE-2010-3760, ZDI-10-188]

A remote attacker can therefore use several vulnerabilities of IBM Tivoli Storage Manager Fastback, in order to create a denial of service or to execute code.
