-------------------------------------------------------------------------

Package : gnutls28 Version : 3.7.1-5+deb11u6 CVE ID : CVE-2024-28834 CVE-2024-28835 Debian Bug : 1067463 1067464

Vulnerabilities have been found in GnuTLS, which could lead to information disclosure or Denial of Service.

CVE-2024-28834

Hubert Kario and George Pantelakis discovered that GnuTLS was vulnerable to a side-channel attack known as the Minerva attack.
In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, the deterministic ECDSA code leaks bit-length of random nonce which allows for full recovery of the private key used after observing a few hundreds to a few thousands of signatures on known messages.

CVE-2024-28835

It was discovered attempting to verify a specially crafted .pem bundle using the `certtool --verify-chain` command could yield an application clash.

For Debian 11 bullseye, these problems have been fixed in version 3.7.1-5+deb11u6.

We recommend that you upgrade your gnutls28 packages.
