1DescriptionCVE.org
A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing.
AnalysisAI
Out-of-bounds heap read in GNU Binutils linker when processing 32-bit XCOFF files allows local attackers to disclose heap memory and cause denial of service. Affects Red Hat Enterprise Linux 6 through 10, Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation identified at time of analysis; EPSS data unavailable.
