A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.

CVE-2024-28835 [MEDIUM] GnuTLS vulnerabilities
Title: GnuTLS vulnerabilities
Summary: Several security issues were fixed in GnuTLS.
USN-6733-1 fixed vulnerabilities in GnuTLS. This update provides the
corresponding updates for Ubuntu 24.04 LTS.
Original advisory details:
It was discovered that GnuTLS had a timing side-channel when performing
certain ECDSA operations. A remote attacker could possibly use this issue
to recover sensitive information. (CVE-2024-28834)
It was discovered that GnuTLS incorrectly handled verifying certain PEM
bundles. A remote attacker could possibly use this issue to cause GnuTLS to
crash, resulting in a denial of service. This issue only affected Ubuntu
22.04 LTS and Ubuntu 23.10. (CVE-2024-28835)
Instructions: In general, a standard system update will make all the necessary changes.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
