Fedora 39 : perl-CryptX (2023-1f0ac1260e)

critical Nessus Plugin ID 186895

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-1f0ac1260e 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 perl-CryptX package.
