NewStart CGSL CORE 5.05 / MAIN 5.05 : libxslt Multiple Vulnerabilities (NS-SA-2021-0175)

critical Nessus Plugin ID 154558

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, 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.
