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

The vulnerability exists due to insufficient validation of user-supplied input within the bfd_mach_o_get_synthetic_symtab() function in match-o.c in objdump. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

2) Resource exhaustion (CVE-ID: CVE-2022-48063)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 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

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 load_separate_debug_files() function in dwarf2.c. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

3) Memory leak (CVE-ID: CVE-2022-48065)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 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

The vulnerability allows a remote attacker to perform DoS attack on the target system.
