Description

This security bulletin contains information about 10 secuirty vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2025-7546)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the bfd_elf_set_group_contents() function in bfd/elf.c. A local user can trigger an out-of-bounds write and execute arbitrary code on the target system.


2) Heap-based buffer overflow (CVE-ID: CVE-2025-7545)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the copy_section() function in binutils/objcopy.c. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.


3) Buffer overflow (CVE-ID: CVE-2025-11413)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the elf_link_add_object_symbols() function in bfd/elflink.c. A local user can trigger memory corruption and execute arbitrary code on the target system.


4) Buffer overflow (CVE-ID: CVE-2025-11412)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the bfd_elf_gc_record_vtentry() function in bfd/elflink.c. A local user can trigger memory corruption and execute arbitrary code on the target system.


5) Buffer overflow (CVE-ID: CVE-2025-11414)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the get_link_hash_entry() function in bfd/elflink.c. A local user can trigger memory corruption and execute arbitrary code on the target system.


6) Buffer overflow (CVE-ID: CVE-2025-11495)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the elf_x86_64_relocate_section() function in elf64-x86-64.c. A local user can trigger memory corruption and execute arbitrary code on the target system.


7) Buffer overflow (CVE-ID: CVE-2025-11081)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the dump_dwarf_section() function in binutils/objdump.c. A local user can trigger memory corruption and execute arbitrary code on the target system.


8) Heap-based buffer overflow (CVE-ID: CVE-2025-11082)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the _bfd_elf_parse_eh_frame() function in bfd/elf-eh-frame.c. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.


9) Heap-based buffer overflow (CVE-ID: CVE-2025-11083)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the elf_swap_shdr() function in bfd/elfcode.h. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.


10) Buffer overflow (CVE-ID: CVE-2025-11494)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the _bfd_x86_elf_late_size_sections() function in bfd/elfxx-x86.c. A local user can trigger memory corruption and execute arbitrary code on the target system.
