Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Improper check for certificate revocation (CVE-ID: CVE-2024-0853)

The vulnerability allows a remote attacker to bypass OCSP verification.

The vulnerability exists due to curl inadvertently keeps the SSL session ID for connections in its cache even when the verify status (OCSP stapling) test has failed. A subsequent transfer to the same hostname will be successful if the session ID cache is still fresh, which leads to skipping the verify status check. As a result, OCSP verification is always successful for all subsequent TLS sessions.


2) State Issues (CVE-ID: CVE-2023-6129)

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

The vulnerability exists due to an error in POLY1305 MAC (message authentication code) implementation on PowerPC CPU based platforms if the CPU provides vector instructions. A remote attacker can perform a denial of service (DoS) attack.
