Details
A vulnerability classified as problematic has been found in IBM DB2 High Performance Unload up to 6.5.0.0 IF1. Affected is some unknown processing. The manipulation with an unknown input leads to a use of sizeof() on a pointer type vulnerability. CWE is classifying the issue as CWE-467. The code calls sizeof() on a malloced pointer type, which always returns the wordsize/8. This can produce an unexpected result if the programmer intended to determine how much memory has been allocated. This is going to have an impact on availability. CVE summarizes:
IBM DB2 High Performance Unload 6.1.0.3, 5.1.0.1, 6.1.0.2, 6.5, 6.5.0.0 IF1, 6.1.0.1, 6.1, and 5.1 could allow an authenticated user to cause the program to crash due to the incorrect calculation of the size of the data that is being pointed to.
The advisory is available at ibm.com. This vulnerability is traded as CVE-2025-33132 since 04/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The technical details are unknown and an exploit is not available.
