Summary

gdb security update

Details

GDB, the GNU Project debugger, allows you to see what is going on inside another program while it executes -- or what another program was doing at the moment it crashed.

Security Fix(es):

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.(CVE-2026-15003)
