Description

In Veritas Backup Exec 2014 before build 14.1.1187.1126, 15 before build 14.2.1180.3160, and 16 before FP1, there is a use-after-free vulnerability in multiple agents that can lead to a denial of service or remote code execution. An unauthenticated attacker can use this vulnerability to crash the agent or potentially take control of the agent process and then the system it is running on.

• CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
