{"id":"UBUNTU-CVE-2024-0553","details":"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.","modified":"2026-04-22T14:35:39.475852Z","published":"2024-01-16T12:15:00Z","related":["USN-6593-1"],"upstream":["CVE-2024-0553"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-0553"},{"type":"REPORT","url":"https://gnutls.org/security-new.html#GNUTLS-SA-2024-01-14"},{"type":"REPORT","url":"https://lists.gnupg.org/pipermail/gnutls-help/2024-January/004841.html"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2024-0553"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6593-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-0553"}],"affected":[{"package":{"name":"gnutls28","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.4.10-4ubuntu1.9+esm2?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.15-5ubuntu2","3.3.18-1ubuntu1","3.3.20-1ubuntu1","3.4.9-2ubuntu1","3.4.10-4ubuntu1","3.4.10-4ubuntu1.1","3.4.10-4ubuntu1.2","3.4.10-4ubuntu1.3","3.4.10-4ubuntu1.4","3.4.10-4ubuntu1.5","3.4.10-4ubuntu1.6","3.4.10-4ubuntu1.7","3.4.10-4ubuntu1.8","3.4.10-4ubuntu1.9","3.4.10-4ubuntu1.9+esm1","3.4.10-4ubuntu1.9+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.10-4ubuntu1.9+esm2","binary_name":"gnutls-bin"},{"binary_version":"3.4.10-4ubuntu1.9+esm2","binary_name":"guile-gnutls"},{"binary_version":"3.4.10-4ubuntu1.9+esm2","binary_name":"libgnutls-openssl27"},{"binary_version":"3.4.10-4ubuntu1.9+esm2","binary_name":"libgnutls30"},{"binary_version":"3.4.10-4ubuntu1.9+esm2","binary_name":"libgnutlsxx28"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-0553.json"}},{"package":{"name":"gnutls28","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.5.18-1ubuntu1.6+esm2?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.8-6ubuntu3","3.5.17-1ubuntu1","3.5.17-1ubuntu3","3.5.18-1ubuntu1","3.5.18-1ubuntu1.1","3.5.18-1ubuntu1.2","3.5.18-1ubuntu1.3","3.5.18-1ubuntu1.4","3.5.18-1ubuntu1.5","3.5.18-1ubuntu1.6","3.5.18-1ubuntu1.6+esm1","3.5.18-1ubuntu1.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.5.18-1ubuntu1.6+esm2","binary_name":"gnutls-bin"},{"binary_version":"3.5.18-1ubuntu1.6+esm2","binary_name":"libgnutls-dane0"},{"binary_version":"3.5.18-1ubuntu1.6+esm2","binary_name":"libgnutls-openssl27"},{"binary_version":"3.5.18-1ubuntu1.6+esm2","binary_name":"libgnutls30"},{"binary_version":"3.5.18-1ubuntu1.6+esm2","binary_name":"libgnutlsxx28"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-0553.json"}},{"package":{"name":"gnutls28","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.6.13-2ubuntu1.10?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.6.13-2ubuntu1.10"}]}],"versions":["3.6.9-5ubuntu1","3.6.9-5ubuntu2","3.6.10-5","3.6.11.1-2","3.6.11.1-2ubuntu2","3.6.13-2ubuntu1","3.6.13-2ubuntu1.1","3.6.13-2ubuntu1.2","3.6.13-2ubuntu1.3","3.6.13-2ubuntu1.6","3.6.13-2ubuntu1.7","3.6.13-2ubuntu1.8","3.6.13-2ubuntu1.9"],"ecosystem_specific":{"binaries":[{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"gnutls-bin"},{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"guile-gnutls"},{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"libgnutls-dane0"},{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"libgnutls-openssl27"},{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"libgnutls30"},{"binary_version":"3.6.13-2ubuntu1.10","binary_name":"libgnutlsxx28"}],"availability":"No
