PACKAGE :mpack SUMMARY :remote buffer overflow DATE :2002-08-02 12:15 UTC
--------------------------------------------------------------------
OVERVIEW
A buffer overflow in the munpack program causes the program to crash and might also be used to run arbitary code.
There also exist a second vulnerability that affects malformed filenams.
DETAIL
- From Debian Security Advisory DSA 141-1:
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).
The full Debian Security Advisory can be read at http://security.debian.org NOTE: The DSA was not uploaded at the time when this advisory was written.
SOLUTION
It is recommended that all Gentoo Linux users update their systems as follows.
emerge rsync emerge mpack emerge clean
