NewStart CGSL MAIN 6.02 : libxslt Multiple Vulnerabilities (NS-SA-2021-0088)

critical Nessus Plugin ID 147289

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has libxslt packages installed that are affected by multiple vulnerabilities:

- libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)

- 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL libxslt packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
