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):

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.36. It is a stack-overflow issue in demangle_type in rust-demangle.c.(CVE-2021-32256)

A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended to deploy a patch. The code maintainer replied with [f]ixed for 2.46 .(CVE-2025-11083)
