EulerOS 2.0 SP5 : libxslt (EulerOS-SA-2019-2541)

high Nessus Plugin ID 131815

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libxslt packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- This C library allows to transform XML files into other XML files (or HTML, text, ...) using the standard XSLT stylesheet transformation mechanism. To use it you need to have a version of libxml2 >= 2.6.27 installed. The xsltproc command is a command line interface to the XSLT engine.Security Fix(es):In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.(CVE-2019-18197)

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 libxslt package.
