EulerOS Virtualization 2.10.1 : shim (EulerOS-SA-2026-1146)
medium Nessus Plugin ID 297388
Synopsis
The remote EulerOS Virtualization host is missing a security update.Description
According to the versions of the shim packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption.
The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.(CVE-2022-4304)
Tenable has extracted the preceding description block directly from the EulerOS Virtualization shim security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
