Debian DSA-141-1 : mpack - buffer overflow

medium Nessus Plugin ID 14978

Synopsis

The remote Debian host is missing a security-related update.

Description

Eckehard Berns discovered a buffer overflow in the munpack program which is used for decoding (respectively) binary files in MIME (Multipurpose Internet Mail Extensions) format mail messages. If munpack is run on an appropriately malformed email (or news article) then it will crash, and perhaps can be made to run arbitrary code.

Herbert Xu reported a second vulnerability which affected malformed filenames that refer to files in upper directories like '../a'. The security impact is limited, though, because only a single leading '../' was accepted and only new files can be created (i.e. no files will be overwritten).

Both problems have been fixed in version 1.5-5potato2 for the old stable distribution (potato), in version 1.5-7woody2 for the current stable distribution (woody) and in version 1.5-9 for the unstable distribution (sid).

Solution

Upgrade the mpack package immediately.
