Description
This security bulletin contains information about 1 security vulnerability.
1) Heap-based buffer over-read (CVE-ID: CVE-2018-10372)
The vulnerability allows a remote unauthenticated attacker to cause Dos condition on the target system.
The weakness exists in the process_cu_tu_index function in the dwarf.c source code file due to improper bounds checking when used to process binary files. A remote attacker can trick the victim into opening a specially crafted binary file, as demonstrated by readelf, trigger heap-based buffer overread and cause the service to crash.
