Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions GNU Binutils version 2.30

Description The issue is related to the bfd section from shdr function in the elf.c component of the Binary File Descriptor (BFD) library. It allows remote attackers to cause a denial of service, resulting in a segmentation fault, via a large attribute section. This is due to insufficient input validation.

Recommendations For GNU Binutils version 2.30, consider applying a patch or fix that addresses the insufficient input validation in the bfd section from shdr function to prevent denial of service attacks. As a temporary workaround, consider restricting the size of attribute sections to prevent large sections from causing a segmentation fault.
