EUVDB-ID: #VU56064

Risk: Medium

CVSSv4.0: 2.7 [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]

CVE-ID: CVE-2021-3712

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

Mitigation

Update the affected package openssl-1_0_0 to the latest version.
