EulerOS 2.0 SP8 : gnutls (EulerOS-SA-2024-2467)

critical Nessus Plugin ID 207621

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the gnutls packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 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.(CVE-2024-0553)

 A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.(CVE-2023-5981)

Tenable has extracted the preceding description block directly from the EulerOS gnutls security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected gnutls packages.
