Name of the Vulnerable Software and Affected Versions
GNU Binutils version 2.30
Description
The issue allows attackers to cause a denial of service or possibly have other impacts, as demonstrated by an out-of-bounds write of 8 bytes during the execution of objdump. This can occur due to a heap-based buffer overflow. Exploitation of the issue may allow a remote attacker to access confidential data, disrupt its integrity, and cause a denial of service.
Recommendations
For GNU Binutils version 2.30, consider updating to a newer version that contains a fix for this issue, as using the
finish stab function in stabs.c can lead to a heap-based buffer overflow. As a temporary workaround, consider disabling the finish stab function until a patch is available.Exploit
