high Nessus Plugin ID 201709

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of p7zip installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2018-5996 advisory.

 - Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, allows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
 (CVE-2018-5996)

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