Name of the Vulnerable Software and Affected Versions GNU Binutils versions (affected versions not specified)

Description A flaw exists in the GNU Binutils BFD library, a component used for handling binary files. The issue arises when processing specially crafted XCOFF object files, specifically due to improper validation of a relocation type value before use. This can lead to out-of-bounds memory reads, potentially causing tools to crash or reveal unintended memory contents. This could result in denial-of-service or limited information disclosure.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
