EulerOS Virtualization 2.9.0 : libtomcrypt (EulerOS-SA-2021-2196)

critical Nessus Plugin ID 151545

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the libtomcrypt package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - In LibTomCrypt through 1.18.2, the der_decode_utf8_string function (in der_decode_utf8_string.c) does not properly detect certain invalid UTF-8 sequences. This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locations via carefully crafted DER-encoded data.(CVE-2019-17362)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libtomcrypt package.
