Apache HTTP Server 2.0.47 released

Today the Apache Software Foundation and the Apache HTTP Server Project have announced the release of the Apache HTTP Server 2.0.47. This release fixes four security vulnerabilities:
  • Certain sequences of per-directory renegotiations and the SSLCipherSuite directive being used to upgrade from a weak ciphersuite to a strong one could result in the weak ciphersuite being used in place of the strong one. [CAN-2003-0192]

  • Certain errors returned by accept() on rarely accessed ports could cause temporal denial of service, due to a bug in the prefork MPM. [CAN-2003-0253]

  • Denial of service was caused when target host is IPv6 but ftp proxy server can't create IPv6 socket. [CAN-2003-0254]

  • The server would crash when going into an infinite loop due to too many subsequent internal redirects and nested subrequests. [VU#379828]
The release is available for download now. We'll pass along vendor updates as we see them.

teapop: SQL injection

Package(s):teapop CVE #(s):CAN-2003-0515
Created:July 9, 2003 Updated:October 1, 2003
Description: teapop, a POP-3 server, includes modules for authenticating users against a PostgreSQL or MySQL database. These modules do not properly escape user-supplied strings before using them in SQL queries. This vulnerability could be exploited to execute arbitrary SQL under the privileges of the database user as which teapop has authenticated.

Description: semi, a MIME library for GNU Emacs, does not take appropriate security precautions when creating temporary files. This bug could potentially be exploited to overwrite arbitrary files with the privileges of the user running Emacs and semi, potentially with contents supplied by the attacker.

wemi is a fork of semi, and contains the same bug.

bind buffer overflow vulnerability in DNS resolver libraries

Package(s):bind glibc CVE #(s):CAN-2002-0651 CAN-2002-0684
Created:July 8, 2002 Updated:October 1, 2003
Description: The BIND 4.9.8-OW2 patch and BIND 4.9.9 release (and thus 4.9.9-OW1) include fixes for a libc related vulnerability which does not affect Linux. Updates from the Internet Software Consortium (ISC) are available from here.

No release or branch of Openwall GNU/*/Linux (Owl) is known to be affected, due to Olaf Kirch's fixes for this problem getting into the GNU C library more than two years ago.

Unfortunatly that does not mean that Linux systems are not vulnerable. Similar code, without Olaf Firch's fixes, is in the glibc getnetbyXXX functions. These functions are described in the SuSE alert as " used by very few applications only, such as ifconfig and ifuser, which makes exploits less likely."

Canna server: exploitable buffer overrun

Package(s):canna CVE #(s):CAN-2002-1158 CAN-2002-1159
Created:December 10, 2002 Updated:October 1, 2003
Description: Canna is a kana-kanji conversion server which is necessary for Japanese language character input.

A buffer overflow bug in the Canna server up to and including version 3.5b2 allows a local user to gain the privileges of the user 'bin' which could lead to further exploits. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-1158 to this issue.

A lack of validation of requests has been found that affects Canna version 3.6 and earlier. A malicious remote user could exploit this vulnerability to leak information, or cause a denial of service attack. (CAN-2002-1159)

CUPS: vulnerability in the CUPS IPP implementation

Package(s):cups CVE #(s):CAN-2003-0195
Created:May 27, 2003 Updated:July 22, 2003
Description: Phil D'Amore of Red Hat discovered a vulnerability in the CUPS IPP (Internet Printing Protocol) implementation. The IPP implementation is single-threaded, which means only one request can be serviced at a time. An attacker could make a partial request that does not time out and therefore creates a denial of service. In order to exploit this bug, an attacker must have the ability to make a TCP connection to the IPP port (by default 631).

glibc: DNS stub resolvers contain buffer overflow vulnerability

Package(s):glibc CVE #(s):CAN-2002-1146
Created:November 7, 2002 Updated:February 5, 2004
Description: DNS stub resolvers from multiple vendors contain a buffer overflow vulnerability. The impact of this vulnerability appears to be limited to denial of service. (See CERT Vulnerability Note VU#738331)

The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, uses the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).

kernel-utils: setuid vulnerability

Package(s):kernel-utils CVE #(s):CAN-2003-0019
Created:February 7, 2003 Updated:January 21, 2005
Description: The kernel-utils package contains several utilities that can be used to control the kernel or machine hardware. In Red Hat Linux 8.0 this package contains user mode linux (UML) utilities.

The uml_net utility in kernel-utils packages with Red Hat Linux 8.0 was incorrectly shipped setuid root. This could allow local users to control certain network interfaces, add and remove arp entries and routes, and put interfaces in and out of promiscuous mode.

All users of the kernel-utils package should update to these packages that contain a version of uml_net that is not setuid root.

Alternatively, as a work-around to this vulnerability issue the following command as root:

chmod -s /usr/bin/uml_net

This could be used by a local attacker to gain access to an administrator's X session.

wget:directory traversal bug

Package(s):wget CVE #(s):CAN-2002-1344
Created:December 10, 2002 Updated:October 1, 2003
Description: Versions of wget prior to 1.8.2-4 contain a bug that permits a malicious FTP server to create or overwrite files anywhere on the local file system.

FTP clients must check to see if an FTP server's response to the NLST command includes any directory information along with the list of filenames required by the FTP protocol (RFC 959, section 4.1.3).

If the FTP client fails to do so, a malicious FTP server can send filenames beginning with '/' or containing '/../' which can be used to direct a vulnerable FTP client to write files (such as .forward, .rhosts, .shosts, etc.) that can then be used for later attacks against the client machine.
