Updated sudo packages fixing a security problem are available.

New groff packages have been made available that fix an overflow in groff. If the printing system running this is a security issue, it is recommended to update to the new, fixed packages.

Sebastian Krahmer from SuSE found a vulnerability in sudo which could easily lead into a local root exploit.

Larry McVoy found a bug in the packet handling code for the CIPE VPN package: it did not check if a received packet was too short and could crash.

The SuSE Security Team discovered a bug in the sudo program which is installed setuid to root. Attackers may trick "sudo" to log failed sudo invocations executing the sendmail program with root-privileges and not completely cleaned environment. Depending on the installed mail-package this may enable attackers to execute code as root. This is the case for at least the postfix mailer. Other mailers may be exploited in a similar way. This bug has been fixed by having "sudo" invoke the sendmail command with user-privileges instead. Please update your sudo package regardless of the mail-packages you are using. As a temporary workaround you may remove the s-bit from sudo with the "chmod -s `which sudo`" command, which will disable the sudo functionality.

A buffer overflow has been found in the globbing code for glibc. This code which is used to glob patterns for filenames and is commonly used in applications like shells and FTP servers.

Pine 4.44 packages are now available to fix a problem with insecure URL handling.

A buffer overflow has been found in the glob(3) function in glibc. Fixed packages for Slackware 8.0 are now available.

New mutt packages that fix an overflow in mutt's address parsing code are available. It is recommended that all mutt users update to the fixed packages.

Updated namazu packages are available for Red Hat Linux 7.0J. These packages fix cross-site scripting vulnerabilities. It also fixes a possible buffer overflow.

There are some insecure permissions on configuration files and executables with the bind 9.x packages shipped with Mandrake Linux 8.0 and 8.1. This update provides stricter permissions by making the /etc/rndc.conf and /etc/rndc.key files read/write by the named user and by making /sbin/rndc-confgen and /sbin/rndc read/write/executable only by root.

Joost Pol reported a remotely exploitable buffer overflow in the mutt email client. It is recommended that all mutt users upgrade their packages immediately.

Flavio Veloso found an overflowable buffer problem in earlier versions of the glibc glob(3) implementation. It may be possible to exploit some programs that pass input to the glibc glob() function in a manner that can be modified by the user. Update: The glibc update for 8.0/PPC resulted in ldconfig segfaulting consistently. This update fixes the problems with ldconfig on PPC.

Two different problems where found in libgtop-daemon:

An exploitable overflow has been found in the address handling code of the mutt mail client version 1.2.5i supplied with Slackware 8.0. A new mutt-1.2.5.1 has been released which addresses this problem, and packages are now available for Slackware 8.0 and -current.

mutt, a popular mail client for Linux-like systems, is vulnerable to a buffer overflow that is remotely exploitable. We have added patches to the versions of mutt as shipped with the affected distributions to fix the problem. We recommend to install the update package for your product and to restart all running instances of mutt. We thank Joost Pol for reporting the problem to the makers of mutt.

Patrice Fournier discovered a bug in all versions of Exim older than Exim 3.34 and Exim 3.952.

The sparc binary for the mutt security fix described in DSA-096-1 is now available.

Joost Pol found a buffer overflow in the address handling code of mutt (a popular mail user agent). Even though this is a one byte overflow this is exploitable.

Updated Mailman packages are now available for Red Hat Secure Web Server 3.2 (U.S.). These updates fix cross-site scripting bugs which might allow another server to be used to gain a user's private information from a server running Mailman.
