Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) NULL pointer dereference (CVE-ID: CVE-2022-4285)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error when parsing an ELF file containing corrupt symbol version information. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.

2) Resource exhaustion (CVE-ID: CVE-2022-48064)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources within the bfd_dwarf2_find_nearest_line_with_alt() function in dwarf2.c. A remote attacker can trigger resource exhaustion via a crafted ELF file and perform a denial of service (DoS) attack.

3) Heap-based buffer overflow (CVE-ID: CVE-2023-1972)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the _bfd_elf_slurp_version_tables() function in bfd/elf.c. A remote attacker can pass specially crafted file to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.

4) NULL pointer dereference (CVE-ID: CVE-2020-16599)

The vulnerability allows a local attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in _bfd_elf_get_symbol_version_string. A local attacker can trick the victim into opening a specially crafted file and perform a denial of service (DoS) attack.
