Summary
Binutils: binutils: denial of service vulnerabilities in readelf via crafted elf files
Details

A flaw was found in the readelf utility of the binutils package. A local attacker could exploit two Denial of Service (DoS) vulnerabilities by providing a specially crafted Executable and Linkable Format (ELF) file. One vulnerability, a resource exhaustion (CWE-400), can lead to an out-of-memory condition. The other, a null pointer dereference (CWE-476), can cause a segmentation fault. Both issues can result in the readelf utility becoming unresponsive or crashing, leading to a denial of service.
