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

Description The issue is related to an integer overflow in the load specific debug section() function in objdump.c. This overflow results in malloc() being called with a size of 0. A crafted ELF file can be used by remote attackers to cause a denial of service, leading to an application crash, or possibly having other unspecified impacts.

Recommendations For GNU Binutils version 2.30, consider updating to a newer version that addresses this issue. As a temporary workaround, restrict the use of the load specific debug section() function in objdump.c to minimize the risk of exploitation. Avoid processing crafted ELF files until the issue is resolved.
