Description Andrej Nemec 2016-05-05 09:46:15 UTC
A vulnerability was found in libiberty when demangling some specific mangled functions. A particularly malicious attacker could craft an executable that executes when *analysed* by objdump, nm or gdb, or any other libiberty-based forensics tool (if the demangling option is switched on).
