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

Name of the Vulnerable Software and Affected Versions GNU Binutils version 2.32

Description The issue is related to an out-of-bounds read in the Binary File Descriptor (BFD) library, specifically in the bfd getl32 function within libbfd.c, which is called from pex64 get runtime function in pei-x86 64.c. This can lead to a segmentation fault. The vulnerability can be exploited by a remote attacker to cause a denial of service.

Recommendations For GNU Binutils version 2.32, consider updating to a newer version that includes a fix for this issue. As a temporary workaround, restrict access to the pex64 get runtime function in pei-x86 64.c to minimize the risk of exploitation. Avoid using the bfd getl32 function in libbfd.c until the issue is resolved.
