______________________________________________________________________________
1) solved security vulnerabilities
To avoid spamming lists with advisories for every small incident,
we will release weekly summary advisories for issues where we have
released updates without a full advisory. Since these are minor
issues, md5sums and ftp URLs are not included.
Fixed packages for the following incidents are already available on
our FTP server and via the YaST Online Update.
- mailman missing dependency
The mailman update from last week introduced new code into
the mailman python code. This code requires python classes from the
python-xml package. Please make sure you have the python-xml
RPM installed if you are using mailman.
- several security problems in CUPS
Several problems in the print system CUPS have been fixed:
- xpdf buffer overflows in included pdftops filter program.
Mitre CVE IDs: CAN-2005-0064 and CAN-2004-1125.
- buffer overflow in hpgltops filter program found by djb students.
Mitre CVE ID: CAN-2004-1267
- lppasswd denial of service attack found by djb students.
Mitre CVE ID: CAN-2004-1268
All SUSE Linux based products are affected.
- multiple Mozilla vulnerabilities
Lots of Mozilla problems have been fixed in the Mozilla and Mozilla
Firefox packages. All currently known security bug fixes from the
Mozilla release branches were merged into our Mozilla RPMs.
All SUSE Linux based products are affected.
- Java Plugin security problems
A privilege escalation problem was found in the Sun Java Plugin
which could have a remote attacker reading and writing files of
a local user browsing websites. This is tracked by the Mitre CVE
ID CAN-2004-1029.
This bug affects all SUSE versions on the Intel x86 and AMD64 /
Intel Extended Memory Architecture (EM64T) platforms.
- Several KDE vulnerabilities
Several vulnerabilities were identified and fixed within KDE:
- Java Plugin security problems similar to the Sun Java Plugin
security problems were identified and fixed.
Mitre CVE ID: CAN-2004-1145
- A FTP command injection problem was identified and fixed.
- Window injection vulnerabilities were identified and fixed.
Mitre CVE ID: CAN-2004-1158
- SMB link URLs could contain the passwords of the shares.
All SUSE Linux based products are affected.
- various phpMyAdmin problems
Several problems were found within phpMyAdmin:
- with PHP safe mode off and external transformations enabled an
attacker could execute arbitrary commands (CAN-2004-1147,
PMASA-2004-4). This only affects SUSE Linux version starting
with 9.0.
- With PHP safe mode off an attacker could read arbitrary files
(CAN-2004-1148, PMASA-2004-4). SUSE Linux versions starting with
8.2 are affected.
- multiple cross site scripting bugs (CAN-2004-1055, PMASA-2004-3)
All SUSE Linux versions are affected.
- clamav denial of service attack
Our system administrators spotted a rogue ZIP file that caused
clamav to crash by a division by zero. This problem was fixed and
is tracked by the Mitre CVE CAN-2005-0133. A further upstream
clamav update is currently in progress.
- libXPM bug fixes
Earlier versions of the bug fix for libXPM buffer overflows had
problems when saving XPM files to absolute pathnames for instance
via GIMP. This problem was fixed and affected all SUSE Linux based
products.
- various ncpfs problems
Erik Sjølund of Debian discovered various ncpfs security problems
which could lead to a local attacker gaining root privileges. These
are tracked by the Mitre CVE IDs CAN-2005-0013 and CAN-2005-0014.
All SUSE Linux based products were affected.
- ImageMagick buffer overflows
ImageMagick contained buffer overflows in the PSD (Photoshop
Document) decoding routines. This is tracked by the Mitre CVE ID
CAN-2005-0005.
All SUSE Linux based products are affected.
- hylafax authentication problems
Lee Howard found a bug in the authentication code of hfaxd
that allowed attackers to gain unauthorized access to the fax
system by guessing the content of the hosts.hfaxd file.
This is tracked by the Mitre CVE ID CAN-2004-1182.
All SUSE Linux based products are affected.
- postfix 64 bit and IPv6 related problems
- When postfix runs chrooted without /proc mounted and has
the permit_mx_backup option set, it would relay mails to any
MX hosts with AAAA (IPv6) DNS records.
This was found and reported by Peer Heinlein.
- When setting "debug_peer_list" to a non-empty value and using
lmtp delivery via unix domain sockets, the postfix lmtp process
will segfault. This bug is only valid on 64bit platforms:
- Postfix components can segfault because of non-portable reuse of
variadic argument lists.
All SUSE Linux based products are affected.
- samba bug fix release
The previous Samba security update contained a bug which could
lead to the smbd crashing on startup.
All SUSE Linux based products are affected.
- various Squid denial of service problems
Various denial of service and potential buffer overflow problems
were found in the web proxy Squid:
- Mitre CVE ID CAN-2005-0094
"infamous41md" discovered a buffer overflow in the parser for
Gopher responses which will lead to memory corruption and usually
crash Squid.
- Mitre CVE ID CAN-2005-0095
"infamous41md" discovered an integer overflow in the receiver of
WCCP (Web Cache Communication Protocol) messages. An attacker
could send a specially crafted UDP datagram that will cause Squid
to crash.
- Mitre CVE ID CAN-2005-0096
Memory leak in the NTLM fakeauth_auth helper for Squid 2.5.STABLE7
and earlier allows remote attackers to cause a denial of service
by memory consumption.
- Mitre CVE ID CAN-2005-0097
The NTLM component in Squid 2.5.STABLE7 and earlier allows remote
attackers to cause a denial of service (crash) via a malformed NTLM
type 3 message.
- Mitre CVE ID CAN-2005-0175 and CAN-2005-0174.
Minor problems in the HTTP header parsing code were fixed.
- CAN-2005-0173
LDAP is very forgiving about spaces in search filters and this could
be abused to log in using several variants of the login name, possibly
bypassing explicit access controls or confusing accounting.
- multiple mc problems
Several bug fixes were applied to the source by upstream developers of
the console file browser mc that are security relevant.
- CAN-2004-1004 Multiple format string vulnerabilities
- CAN-2004-1005 Multiple buffer overflows
- CAN-2004-1009 One infinite loop vulnerability
- CAN-2004-1090 Denial of service via corrupted section header

The xntpd crashes when accessing NTP hosts with IPv6 addresses.
This affects all SUSE linux based platforms.
- various ethereal protocol decoder problems
Various network protocol decoder problems were fixed in ethereal
which could lead to crashes or remote attackers executing code.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum
