Description

This security bulletin contains information about 1 vulnerability.


1) Heap-based buffer over-read (CVE-ID: CVE-2018-10372)

CWE-ID: CWE-126 - Buffer over-read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear


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.
