Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU76453

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-4285

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.

2) Resource exhaustion

EUVDB-ID: #VU86948

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-48064

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.

4) NULL pointer dereference

EUVDB-ID: #VU79354

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-16599

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.
