PACKAGE : samba

EXPLOIT : remote

- From 2.2.7 release notes:

There was a bug in the length checking for encrypted password change
requests from clients. A client could potentially send an encrypted
password, which, when decrypted with the old hashed password could be
used as a buffer overrun attack on the stack of smbd. The attach would
have to be crafted such that converting a DOS codepage string to little
endian UCS2 unicode would translate into an executable block of code.

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-fs/samba-2.2.5-r1 and earlier update their systems as follows:

emerge rsync
emerge samba
emerge clean
