Upstream information
Description
An out-of-bounds write vulnerability was found in the BFD library's DLX ELF backend (bfd/elf32-dlx.c) in GNU binutils. The dlx_rtype_to_howto() function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values (via ELF32_R_TYPE(r_info)) before indexing into the dlx_elf_howto_table[] array. The DLX relocation type number space is non-contiguous (basic types 0-6, extended types at 0x10000+), but the default case in the switch statement allows arbitrary index values to reach the array access.A specially crafted ELF/DLX object file can trigger this out-of-bounds write when processed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). The vulnerability has been demonstrated to achieve arbitrary code execution via a File Stream Oriented Programming (FSOP) attack against glibc FILE structures (stderr), redirecting control flow to system().
Attack scenarios include CI/CD pipelines performing automated binary analysis, developer workstations running objdump/readelf on untrusted binaries, automated security scanning or malware analysis tools invoking binutils, and package build systems processing third-party code.
Note: This vulnerability is only exploitable when binutils is built with the DLX backend enabled (typically via --enable-targets=all).

Note from the SUSE Security Team on the binutils package
SUSE considers binutils a developer tool which does not receive untrusted input. Code processed by binutils is being executed in any normal scenario, so security exploits could just inject regular binary code. For this reason we update binutils only around once a year to the current stable version to catch up on features and bugfixes. If you are processing untrusted binary code with binutils we recommend doing so on a seperate system or VM. SUSE Bugzilla entry: 1274433 [NEW] No SUSE Security Announcements cross referenced.Status of this issue by product and package
