Multiple security vulnerabilities have been identified in the PostgreSQL software shipped with Debian Linux. These vulnerabilities may allow a remote authenticated user with certain privileges to gain extra privileges via a table with a crafted index function. Further vulnerabilities may allow man-in-the-middle attacks on SSL based PostgreSQL servers by substituting malicious SSL certificates for trusted ones. New releases are available now.

|
|
An unauthenticated remote attacker could cause the KDC to crash due to a null pointer dereference.
Legitimate requests can also cause this crash to occur, meaning a Denial-of-Service. A workaround is described in the advisory. The upcoming krb5-1.7.1 release will contain a fix for this vulnerability.

The DNS resolver component in BIND doesn't properly check DNS records contained in additional sections of DNS responses, leading to a cache poisoning vulnerability. This vulnerability is only present in resolvers which have been configured with DNSSEC trust anchors.
Several vulnerabilities have been discovered in kvm, a full virtualization system. They might lead to Denial-of-Service (DoS) and maybe further consequences.
Unbound is a DNS resolver. It doesn't properly check cryptographic signatures on NSEC3 records. As a result, zones signed with the NSEC3 variant of DNSSEC lose their cryptographic protection.
Fixed packages are available now.

A potential security vulnerability has been identified in proftpd, a common FTP server included in Mandriva Linux.
This vulnerability is the well known in SSL and TLS leading to attackers remotely injecting unauthorized data or creating a Denial-of-Service (DoS). A software update addresses this issue.
|
|

An update fixes several security issues and various bugs in the SuSE Linux Enterprise 10 SP 2 kernel.
Exploiting these vulnerablities might lead to the execution of arbitrary code or commands, increased privileges or Denial-of-Service (DoS).
|
|
|
Several vulnerabilities have been found in Firefox, the well known web browser.
Versions before 3.0.16 and 3.5.6 might allow remote execution of code or give attackers the ability to crash the browser. Please use the latest versions only.
|
|
|
A security update was released for the Adobe Flash Player 10. Specially crafted Flash (SWF) files can cause overflows in flash-player. Attackers could potentially exploit that to execute

It was discovered that ganeti, a virtual server cluster manager, doesn't validate the path of scripts passed as arguments to certain commands, which allows local or remote users to execute arbitrary commands on a host acting as a cluster master.
Further on, it has been found out that acpid, the Advanced Configuration and Power Interface event daemon, creates its log file with weak permissions. Due to this, sensitive information might be exposed or abused by a local user to consume all free disk space on the same partition of the file.
Fixed packages are available now.

A flaw has been found in the way GNU Libtool's libltdl library looks for modules to load. It's possible for libltdl to load and run modules from an arbitrary library in the current working directory. If a local attacker could trick a local user into running an application (which uses libltdl) from an attacker-controlled directory containing a malicious Libtool

Two buffer over-read flaws were found in the way Expat handled malformed

It was discovered that acpid could create its log file ("/var/log/acpid")

Two security vulnerabilities have been found in the GNU tar gtar(1) archiving program bundled with Solaris 9, Solaris 10 and OpenSolaris. The first issue is a directory traversal vulnerability that may allow a local or remote unprivileged user who provides a specially crafted archive to overwrite arbitrary files which the user executing gtar(1) has permission to modify. The second issue is a buffer overflow which may allow a local or remote unprivileged user who provides a specially crafted tar archive to execute arbitrary commands with the privileges of the user executing gtar(1) or to cause gtar(1) to crash. The ability to cause a program crash is a type of Denial-of-Service (DoS).
A security vulnerability in the wget(1) command shipped with Solaris may allow a local or remote unprivileged user who provides a specially crafted certificate signed by a legitimate Certification Authority to intercept encrypted HTTP (HTTPS) communication between the wget(1) client and a web server using a man-in-the-middle (MITM) attack.

Multiple security vulnerabilities have been identified in Sun Solaris 10 libexpat, a library for parsing XML files.

The SSL version 3 and TLS protocols support session renegotiation without cryptographically tying the new session parameters to the old parameters. So an attacker who can intercept a TCP connection being used for SSL or TLS can cause the initial session negotiation to take the place of a session renegotiation leading to a man-in-the-middle attack.
The run-time link-editor, rtld, links dynamic executable with their needed libraries at run-time. When running setuid programs rtld will normally remove potentially dangerous environment variables. Due to recent changes in FreeBSD environment variable handling code, a corrupt environment may result in attempts to unset environment variables failing.
An unprivileged user who can execute programs on a system can gain the privileges of any setuid program which he can run, mostly root.
When downloading updates to FreeBSD via 'freebsd-update fetch' or 'freebsd-update upgrade', the freebsd-update(8) utility copies currently installed files into its working directory. A local user can read files which have been updated by freebsd-update(8), even if those files have permissions which would normally not allow users to read them.

Request-tracker is a trouble-ticket system. It's prone to an attack where an attacker with access to the same domain can hijack a user's RT session.
Gforge is a collaborative development tool. Local users are able to perform a Denial-of-Service (DoS) by overwriting aritrary files via a symlink attack.
