medium Nessus Plugin ID 146364

Language:

Synopsis

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

Description

The remote Fedora 32 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-4205e1fc23 advisory.

 - rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons. (CVE-2021-3181)

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 5:mutt package.
