______________________________________________________________________________
1) Solved Security Vulnerabilities
To avoid flooding mailing lists with SUSE Security Announcements for minor
issues, SUSE Security releases weekly summary reports for the low profile
vulnerability fixes. The SUSE Security Summary Reports do not list or
download URLs like the SUSE Security Announcements that are released for
more severe vulnerabilities.
Fixed packages for the following incidents are already available on our FTP
server and via the YaST Online Update.
- cifs-mount/samba
With enabled "wide links" samba follows symbolic links on the server
side, therefore allowing clients to overwrite arbitrary files
(CVE-2010-0926). This update changes the default setting to have
"wide links" disabled by default. The new default only works if
"wide links" is not set explicitly in smb.conf.
Due to a race condition in mount.cifs a local attacker could corrupt
/etc/mtab if mount.cifs is installed setuid root. mount.cifs is not
setuid root by default and it's not recommended to change that
(CVE-2010-0547).
Affected products: SLE 11, openSUSE 11.0-11.2
- compiz-fusion-plugins-main
The expo plugin in Compiz Fusion allowed local users with physical access
to bypass the screen-saver by just dragging it aside. (CVE-2008-6514:
CVSS v2 Base Score: 6.2)
Affected products: SLE 11, openSUSE 11.0-11.2
- cron
This update of cron fixes a race condition in crontab that can be used to
change the time-stamp of arbitrary files while editing the crontab entry.
CVE-2010-0424: CVSS v2 Base Score: 3.6
Additionally the return value of initgroups() is verified now.
Affected products: SLE 10 SP2+SP3 , SLE 11, openSUSE 11.0-11.2,
Moblin 2.0-2.1
- cups
lppasswd when running setuid or setgid still honors environment variables
that specify the location of message files. Local attackers could exploit
that to gather information by using crafted format strings
(CVE-2010-0393).
The previous fix for a use-after-free vulnerability (CVE-2009-3553) was
incomplete (CVE-2010-0302).
Affected products: SLE 11, openSUSE 11.0-11.2, Moblin 2.0-2.1
- ethereal/wireshark
This update of ethereal fixes:
- CVE-2009-4376: Remote attackers could potentially trigger a buffer
overflow in the Daintree SNA file parser.
- CVE-2009-4377: Specially crafted packets could cause the SMB and SMB2
dissector to crash wireshark.
- CVE-2009-2563: Unspecified vulnerability in the Infiniband dissector
allows remote attackers to cause a denial of service.
- CVE-2010-0304: Several buffer overflows in the LWRES dissector.
Affected products: SLES 9, SLE 10 SP2+SP3, SLE 11, openSUSE 11.0-11.2
- krb5
MITKRB5-SA-2010-002: unauthenticated remote attacker could cause a
GSS-API application including the Kerberos administration daemon
(kadmind) to crash.
CVE-2010-0628 has been assigned to this issue.
Affected products: openSUSE 11.2
- mysql
- fixing various security issues (bnc#557669)
- upstream #47320 - checking server certificates (CVE-2009-4028)
- upstream #48291 - error handling in subqueries (CVE-2009-4019)
- upstream #47780 - preserving null_value flag in GeomFromWKB()
(CVE-2009-4019)
- upstream #39277 - symlink behaviour fixed (CVE-2008-7247)
- upstream #32167 - symlink behaviour refixed (CVE-2009-4030)
- fixing remote buffer overflow (CVE-2009-4484)
Affected products: SLE 10 SP2+SP3
- pulseaudio
Due to a race condition in pulseaudio a local attacker could make
pulseaudio change ownership and permissions of arbitrary files.
The problem is only security relevant if pulseaudio is run in
"system mode" which is not the case by default (CVE-2009-1299).
Affected products: openSUSE 11.0-11.2
- squid/squid3
The following vulnerabilities have been fixed in squid:
- CVE-2009-2855: DoS via special crafted auth header
- CVE-2010-0308: DoS via invalid DoS header
Affected products: SLES 9, SLE 10 SP2+SP3, SLE 11, openSUSE 11.0-11.2
- viewvc
Query forms didn't escape user provided input, therefore allowing
cross-site-scripting (XSS) attacks.
CVE-2010-0736 has been assigned to this issue.
Affected products: openSUSE 11.0-11.2

3) Authenticity Verification and Additional Information
- Announcement authenticity verification:
SUSE security announcements are published via mailing lists and on Web
sites. The authenticity and integrity of a SUSE security announcement is
guaranteed by a cryptographic signature in each announcement. All SUSE
security announcements are published with a valid signature.
To verify the signature of the announcement, save it as text into a file
and run the command
gpg --verify <file>
replacing <file> with the name of the file containing the announcement.
The output for a valid signature looks like:
gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team <security@suse.de>"
where <DATE> is replaced by the date the document was signed.
If the security team's key is not contained in your key ring, you can
import it from the first installation CD. To import the key, use the
command
gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc
- Package authenticity verification:
SUSE update packages are available on many mirror FTP servers all over the
world. While this service is considered valuable and important to the free
and open source software community, the authenticity and integrity of a
package needs to be verified to ensure that it has not been tampered with.
The internal RPM package signatures provide an easy way to verify the
authenticity of an RPM package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, replacing <file.rpm> with the
filename of the RPM package downloaded. The package is unmodified if it
contains a valid signature from build@suse.de with the key ID 9C800ACA.
This key is automatically imported into the RPM database (on RPMv4-based
distributions) and the gpg key ring of 'root' during installation. You can
also find it on the first installation CD and included at the end of this
announcement.
- SUSE runs two security mailing lists to which any interested party may
subscribe:
opensuse-security@opensuse.org
- General Linux and SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security+subscribe@opensuse.org>.
opensuse-security-announce@opensuse.org
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security-announce+subscribe@opensuse.org>.
