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.

According to the versions of the binutils packages installed, the EulerOS Virtualization 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)
