Summary

A flaw was found in GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out-of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service.
