The 'at' command reads commands from standard input for execution at a later time specified on the command line. If such an execution time is given in a carefully drafted (but wrong) format, the at command may crash as a result of a surplus call to free(). The cause of the crash is a heap corruption that is exploitable under certain circumstances since the /usr/bin/at command is installed setuid root.

zen-parse found a bug in the current implementation of at which leads into a heap corruption vulnerability which in turn could potentially lead into an exploit of the daemon user.

The SuSE Security Team discovered a vulnerability in sudo that can be exploited to obtain root privilege because sudo is installed setuid root. An attacker could trick sudo to log failed sudo calls executing the sendmail (or equivalent mailer) program with root privileges and an environment that is not completely clean. This problem has been fixed upstream by the author in sudo 1.6.4 and it is highly recommended that all users upgrade regardless of what mailer you are using.

Versions of xchat prior to version 1.8.7 contain a vulnerability which allows an attacker to cause a vulnerable client to execute arbitrary IRC server commands as if the vulnerable user had typed them. This security erratum updates xchat to version 1.8.7, which is not vulnerable to this attack.

Pine (version 4.43 and earlier) as released with all currently supported versions of Red Hat Linux (6.2, 7, 7.1, 7.2), contains a URL handling bug. This bug can allow a malicious attacker to cause arbitrary commands embedded in a URL to be executed on the users system upon attempting to view the URL.

This updated sudo package fixes a potential local root exploit.

A number of security-related bugs have been found in Bugzilla version

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.
