Fedora 35 : xterm (2022-8cf76a9ceb)

critical Nessus Plugin ID 169249

Language:

Synopsis

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

Description

The remote Fedora 35 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2022-8cf76a9ceb advisory.

 - xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions. (CVE-2022-45063)

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 xterm package.
