Detailsinfo

A vulnerability classified as critical has been found in IBM DB2 and DB2 Connect Server up to 11.5.9/12.1.2. This affects an unknown part of the component Db2fm. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

IBM Db2 for Linux 12.1.0, 12.1.1, and 12.1.2 is vulnerable to a stack-based buffer overflow in db2fm, caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.
