CVE-2024-0553 [MEDIUM] CVE-2024-0553: A vulnerability was found in GnuTLS
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.

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.

CVE-2023-5981 GnuTLS vulnerability
Title: GnuTLS vulnerability
Summary: GnuTLS could be made to expose sensitive information over the network.
USN-6499-1 fixed vulnerabilities in GnuTLS. This update provides the
corresponding update for Ubuntu 18.04 LTS.
Original advisory details:
It was discovered that GnuTLS had a timing side-channel when handling
certain RSA-PSK key exchanges. A remote attacker could possibly use this
issue to recover sensitive information.
Instructions: In general, a standard system update will make all the necessary changes.
