Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Heap-based buffer overflow (CVE-ID: CVE-2022-44840)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the find_section_in_set() function in readelf.c. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Heap-based buffer overflow (CVE-ID: CVE-2022-45703)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the display_debug_section() function in readelf.c. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Memory leak (CVE-ID: CVE-2022-47007)

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

The vulnerability exists due memory leak within the stab_demangle_v3_arg() function in stabs.c. A remote attacker can force the application to leak memory and perform denial of service attack.

4) Memory leak (CVE-ID: CVE-2022-47008)

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

The vulnerability exists due memory leak within the make_tempdir() and make_tempname() function in bucomm.c. A remote attacker can trick the victim to pass specially crafted data to the application and and perform denial of service attack.

5) Memory leak (CVE-ID: CVE-2022-47010)

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

The vulnerability exists due memory leak within the pr_function_type(0 function in prdbg.c. A remote attacker can trick the victim to pass specially crafted input to the application and perform denial of service attack.

6) Memory leak (CVE-ID: CVE-2022-47011)

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

The vulnerability exists due memory leak within the parse_stab_struct_fields() function in stabs.c. A remote attacker can trick the victim to pass specially crafted input to the application and perform denial of service attack.
