CVE-2022-2963Public exploit

Memory leak during invalid option handling

Published Oct 14, 2022 · Updated May 15, 2025

Memory leakage in cmdopts_parse in JasPer 3.0.6 allows local users to leave allocated memory reachable by omitting a command-line option argument. The parser reports the missing argument but fails to release an 8,336-byte allocation before badusage terminates the process. Execution of the local jasper command with an option lacking its required argument is necessary; the allocation persists only until immediate process exit, so no continuing service interruption is demonstrated.
