Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Covert Timing Channel (CVE-ID: CVE-2024-13176)

The vulnerability allows a remote attacker to recover a private key.

The vulnerability exists due to a timing side-channel in ECDSA signature computations. A remote attacker can recover the private key and decrypt data.

Successful exploitation of the vulnerability requires that the attacker's process must either be located in the same physical computer or must have a very fast network connection with low latency.


2) Out-of-bounds read (CVE-ID: CVE-2024-5535)

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

The vulnerability exists due to a boundary condition within the SSL_select_next_proto() function when using NPN. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.
