Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Unchecked Return Value (CVE-ID: CVE-2025-11839)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked return value within the tg_tag_type() function in prdbg.c. A local user can pass specially crafted input to the application and perform a denial of service attack.
2) Buffer overflow (CVE-ID: CVE-2025-11840)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to a boundary error within the vfinfo() function in ldmisc.c. A local user can trigger memory corruption and perform a denial of service attack.
3) Memory leak (CVE-ID: CVE-2025-8225)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due memory leak within the process_debug_info() function in binutils/dwarf.c. A local user can force the application to leak memory and perform denial of service attack.
4) Buffer overflow (CVE-ID: CVE-2025-5244)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the elf_gc_sweep() function in bfd/elflink.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
5) Buffer overflow (CVE-ID: CVE-2025-5245)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the debug_type_samep() function in /binutils/debug.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
6) Memory leak (CVE-ID: CVE-2025-3198)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the display_info() function in binutils/bucomm.c. A remote attacker can force the application to leak memory and perform denial of service attack.
7) Buffer overflow (CVE-ID: CVE-2025-1182)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the bfd_elf_reloc_symbol_deleted_p() function in bfd/elflink.c within the ld binary. A remote attacker can pass specially crafted input to the binary, trigger memory corruption and execute arbitrary code on the target system.
8) Buffer overflow (CVE-ID: CVE-2025-1181)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the _bfd_elf_gc_mark_rsec() function in bfd/elflink.c within the ld binary. A remote attacker can pass specially crafted input to the binary, trigger memory corruption and execute arbitrary code on the target system.
9) Buffer overflow (CVE-ID: CVE-2025-1153)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the bfd_set_format() function in format.c. A local user can trigger memory corruption and execute arbitrary code on the target system.
10) Stack-based buffer overflow (CVE-ID: CVE-2025-0840)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the disassemble_bytes() function in binutils/objdump.c within the nm binary. A remote attacker can pass specially crafted input to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) 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.
