NewStart CGSL CORE 5.04 / MAIN 5.04 : libX11 Multiple Vulnerabilities (NS-SA-2019-0196)

critical Nessus Plugin ID 129928

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has libX11 packages installed that are affected by multiple vulnerabilities:

 - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault). (CVE-2018-14598)

 - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution. (CVE-2018-14600)

 - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact. (CVE-2018-14599)

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 libX11 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
