Exim < 4.83 Math Comparison Functions Data Insertion

Medium Nessus Plugin ID 77055


The remote mail server is potentially affected by a data insertion vulnerability.


According to its banner, the version of Exim running on the remote host is prior to 4.83. It is, therefore, potentially affected by a data insertion vulnerability. A flaw exists in the expansion of arguments to math comparison functions which can cause values to be expanded twice. This could permit a local attacker to insert arbitrary data.


Upgrade to Exim 4.83 or later.
