The kernel in Red Hat Linux 7.1, 7.1K, 7.2, 7.3, and 8.0 are vulnerable to a local denial of service attack. Updated packages are available which address this vulnerability, as well as bugs in several drivers.

A problem in the Courier sqwebmail package, a CGI program to grant authenticated access to local mailboxes, has been discovered. The program did not drop permissions fast enough upon startup under certain circumstances so a local shell user can execute the sqwebmail binary and manage to read an arbitrary file on the local filesystem.

[Bind version 9, the bind9 package, is not affected by these problems.]

Several vulnerabilities were discovered in the BIND8 DNS server by ISS (Internet Security Services), including a remotely exploitable buffer overflow. The first vulnerability is how named handles SIG records; this buffer overflow can be exploited to obtain access to the victim host with the privilege of the user the named process is running as. By default, Mandrake Linux is configured to run the named process as the named user. To successfully exploit this vulnerability, the attacker must control an existing DNS domain and must be allowed to perform a recursive query.

The security research company ISS (Internet Security Services) has discovered several vulnerabilities in the BIND8 name server, including a remotely exploitable buffer overflow.

According to David Wagner, iDEFENSE and the Apache HTTP Server Project, several vulnerabilities have been found in the Apache server package, a commonly used webserver. Most of the code is shared between the Apache and Apache-Perl packages, so vulnerabilities are shared as well.

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. Three remotely exploitable vulnerabilities were disclosed by ISC on 12 November 2002 that affect various versions of BIND 4 and 8.

A set of buffer overflows have been discovered in masqmail, a mail transport agent for hosts without permanent internet connection. In addition to this privileges were dropped only after reading a user supplied configuration file. Together this could be exploited to gain unauthorized root access to the machine on which masqmail is installed.

Traceroute is a tool that can be used to track packets in a TCP/IP network to determine it's route or to find out about not working routers. Traceroute-nanog requires root privilege to open a raw socket. It does not relinquish these privileges after doing so. This allows a malicious user to gain root access by exploiting a buffer overflow at a later point.

During a security review, the SuSE security team has found two vulnerabilities in the KDE lanbrowsing service.

PHP versions up to and including 4.

iDEFENSE reports a security vulnerability in the klisa package, that provides a LAN information service similar to "Network Neighbourhood", which was discovered by Texonet. It is possible for a local attacker to exploit a buffer overflow condition in resLISa, a restricted version of KLISa. The vulnerability exists in the parsing of the LOGNAME environment variable, an overly long value will overwrite the instruction pointer thereby allowing an attacker to seize control of the executable.

The security update for Squirrelmail (DSA 191-1) unfortunately introduced a bug in the options page. This problem is fixed in version 1.2.6-1.2 the current stable distribution (woody). The unstable distribution (sid) and the old stable distribution (potato) were not affected by this. For completeness please find below the original security advisory:

The SuSE Security Team found a vulnerability in html2ps, a HTML to PostScript converter, that opened files based on unsanitized input insecurely. This problem can be exploited when html2ps is installed as filter within lrpng and the attacker has previously gained access to the lp account.

A vulnerability was discovered in Mail::Mailer perl module by the SuSE security team during an audit. The vulnerability allows remote attackers to execute arbitrary commands in certain circumstances due to the usage of mailx as the default mailer, a program that allows commands to be embedded in the mail body.

A buffer overflow vulnerability exists in nss_ldap versions prior to 198. When nss_ldap is configured without a value for the "host" keyword, it attempts to configure itself using SRV records stored in DNS. nss_ldap does not check that the data returned by the DNS query will fit into an internal buffer, thus exposing it to an overflow.

Several cross site scripting vulnerabilities have been found in squirrelmail, a feature-rich webmail package written in PHP4. The Common Vulnerabilities and Exposures (CVE) project identified the following vulnerabilities:

A remotely exploitable stack buffer overflow has been found in the Kerberos v4 compatibility administration daemon distributed with the Red Hat Linux krb5 packages.

Al Viro found a problem in the image handling code use in Window Maker, a popular NEXTSTEP like window manager. When creating an image it would allocate a buffer by multiplying the image width and height, but did not check for an overflow. This makes it possible to overflow the buffer. This could be exploited by using specially crafted image files (for example when previewing themes).

Updated glibc packages are available to fix a buffer overflow in the resolver.
