5) Out-of-bounds read

EUVDB-ID: #VU95131

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-7264

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the ASN1 parser code in the GTime2str() function. A remote attacker can trigger an out-of-bounds read error and cause a denial of service condition on the system.

Mitigation

Install update from vendor's website.
