Following security issues were fixed: CVE-2009-3939: A sysctl variable of the megaraid_sas driver was world writable, allowing local users to cause a denial of service or potential code execution. CVSS v2 Base Score: 6.6 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:C/A:C) CVE-2009-3889: The dbg_lvl file for the megaraid_sas driver in the Linux kernel before 2.6.27 has world-writable permissions, which allows local users to change the (1) behavior and (2) logging level of the driver by modifying this file. This was already fine in SLES 10 SP3 GA due to a driver update of the megaraid_sas driver and is just listed for completeness here. CVSS v2 Base Score: 4.6 (MEDIUM) (AV:L/AC:L/Au:N/C:P/I:P/A:P) CVE-2009-4005: The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel before 2.6.32-rc7 allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read. This requires the attacker to be able to send ISDN low level frames to the host. CVSS v2 Base Score: 7.2 (HIGH) (AV:L/AC:L/Au:N/C:C/I:C/A:C) CVE-2009-3080: A negative offset in a ioctl in the GDTH RAID driver was fixed. CVSS v2 Base Score: 7.2 (HIGH) (AV:L/AC:L/Au:N/C:C/I:C/A:C) CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack. CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C) CVE-2009-2903: Memory leak in the AppleTalk subsystem in the Linux kernel when the AppleTalk and ipddp modules are loaded but the ipddp"N" device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. CVSS v2 Base Score: 7.1 (AV:N/AC:M/Au:N/C:N/I:N/A:C) CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C) CVE-2009-3612 / CVE-2005-4881: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue existed because of an incomplete fix for CVE-2005-4881. CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:C/I:N/A:N) CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:N/I:N/A:C) CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. CVSS v2 Base Score: 7.8 (HIGH) (AV:N/AC:L/Au:N/C:N/I:N/A:C) The rio and sx serial multi port card drivers were disabled via a modprobe blacklist due to severe bugs.

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 where you saved 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@xxxxxxx>" 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 the 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@xxxxxxx 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 at the end of this announcement. - - SUSE runs two security mailing lists to which any interested party may subscribe: opensuse-security@xxxxxxxxxxxx - - 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@xxxxxxxxxxxx>. opensuse-security-announce@xxxxxxxxxxxx - - SUSE's announce-only mailing list.
