The version of IBM Tivoli Storage Manager FastBack running on the remote host is 6.1.x prior to 6.1.11.1. It is, therefore, affected by multiple vulnerabilities :
A flaw exists in the mount service due to improper validation of user-supplied input to the CRYPTO_S_EncryptBufferToBuffer() function. A remote, unauthenticated attacker can exploit this flaw, via a series of specially crafted packets, to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2015-0120)
An overflow condition exists in the mount service due to improper bounds checking. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1896)
An overflow condition exists in the mount service due to improper bounds checking. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1898)
