EulerOS 2.0 SP13 : binutils (EulerOS-SA-2026-2323)

high Nessus Plugin ID 320265

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of- bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service.(CVE-2026-3441)

 GNU Binutils thru 2.46 readelf contains a null pointer dereference vulnerability when processing a crafted ELF binary with malformed header fields. During relocation processing, an invalid or null section pointer may be passed into display_relocations(), resulting in a segmentation fault (SIGSEGV) and abrupt termination. No evidence of memory corruption beyond the null pointer dereference, nor any possibility of code execution, was observed.(CVE-2025-69649)

 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.(CVE-2026-3442)

 GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an abort (SIGABRT) when processing a crafted ELF binary with malformed DWARF abbrev or debug information. Due to incomplete state cleanup in process_debug_info(), an invalid debug_info_p state may propagate into DWARF attribute parsing routines.
 When certain malformed attributes result in an unexpected data length of zero, byte_get_little_endian() triggers a fatal abort. No evidence of memory corruption or code execution was observed; the impact is limited to denial of service.(CVE-2025-69652)

 A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.(CVE-2026-4647)

Tenable has extracted the preceding description block directly from the EulerOS binutils security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected binutils packages.
