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.

A flaw has been discovered in GnuTLS where an application crash can be induced when attempting to verify a specially crafted .pem bundle using the "certtool --verify-chain" command.
A flaw has been discovered in GnuTLS where an application crash can be induced when attempting to verify a specially crafted .pem bundle using the "certtool --verify-chain" command.
Statement: The observed crash in GnuTLS during certificate chain verification, triggered by a specific certificate configuration, represents a moderate severity issue due to its potential impact on security-critical operations reliant on certificate validation. The crash may indicate an underlying flaw in GnuTLS's handling of certain certificate attributes or structures,

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.
