| Vetor | AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
GNU Binutils versions prior to 2.40
Description
The issue is related to excessive memory consumption via the
load separate debug files function at dwarf2.c. An attacker could supply a crafted ELF file, potentially leading to a DNS attack. The vulnerability can be exploited by a remote attacker who provides a specially crafted ELF file.Recommendations
For GNU Binutils versions prior to 2.40, update to version 2.40 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
load separate debug files function in dwarf2.c to minimize the risk of exploitation. Avoid processing untrusted ELF files until the issue is resolved.Exploit
