Package        : gnutls28
Version        : 3.6.7-4+deb10u12
CVE ID         : CVE-2024-0553
Debian Bug     : 1061046

Hubert Kario discovered that GnuTLS, a portable library which implements
the Transport Layer Security and Datagram Transport Layer Security
protocols, was vulnerable to timing side-channel attack in the RSA-PSK
key exchange, which could lead to leakage of sensitive data.  The issue
stems from an incomplete resolution for CVE-2023-5981.

This vulnerability is also known as GNUTLS-SA-2024-01-14.

For Debian 10 buster, this problem has been fixed in version
3.6.7-4+deb10u12.

We recommend that you upgrade your gnutls28 packages.
