Description


A vulnerability has been reported in IBM Tivoli Storage Manager (TSM) Client, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

The vulnerability is caused due to an input validation error within dsmcad.exe, which can be exploited to cause a heap-based buffer overflow by sending a specially crafted packet via TCP.

Successful exploitation allows execution of arbitrary code.

The vulnerability affects the Client Acceptor Daemon (CAD) and the Backup-Archive client scheduler and scheduler service when the option "SCHEDMODE" is set to "PROMPTED".
