MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
A vulnerability in the BFD library of GNU Binutils fails to validate relocation type values when processing crafted XCOFF object files, leading to out-of-bounds memory reads. This can cause tool crashes or limited memory disclosure.
Risk Assessment
An attacker could trigger denial-of-service (DoS) in tools using the BFD library or cause limited memory leaks, potentially exposing sensitive data from the process memory.
Recommendation
Update GNU Binutils to a patched version immediately and avoid processing untrusted XCOFF files on older versions.
Original NVD description (English source)
A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.
