Bug advisoryhttp://www.securityfocus.com/archive/1/335790
Bug affectedExim MTA 3.0 to 4.20
Bug not affectedExim MTA 4.20 and newer
Bug vulnerability classBuffer Overflow
Bug descriptionExim is an well-known open-source Mail Transfer Agent (MTA) for Unix systems. Due to insufficient bounds checking when handling user-supplied SMTP EHLO/HELO data a heap corruption can occur. It may be possible to overrun the bounds of a heap memory buffer and run arbritrary code with server privileges. It may also possible to cause a denial of service.
Bug solutionPatches have been released for Exim version 3.36 and 4.20. The vendor has reported that these patches will likely work on earlier versions as well. Users are advised to upgrade as soon as possible to version 4.21 or newer.
