CBL Mariner 2.0 Security Update: libtomcrypt (CVE-2019-17362)

critical Nessus Plugin ID 201627

Synopsis

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

Description

The version of libtomcrypt 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-2019-17362 advisory.

 - In LibTomCrypt through 1.18.2, the der_decode_utf8_string function (in der_decode_utf8_string.c) does not properly detect certain invalid UTF-8 sequences. This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locations via carefully crafted DER-encoded data. (CVE-2019-17362)

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

Solution

Update the affected packages.
