1) Out-of-bounds read (CVE-ID: CVE-2021-35940)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to a boundary condition in the "apr_time_exp*()" functions. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

Note, the vulnerability exists due to a missing patch for #VU9477 (CVE-2017-12613).
