Secunia Research has discovered a vulnerability in Autonomy KeyView, which can be exploited by malicious people to potentially compromise a vulnerable system. The vulnerability is caused by an error in the SpreadSheet Lotus 123 reader (wkssr.dll) when allocating an array of pointers during the parsing of a certain record type combined with how strings are later indexed. This can be exploited to corrupt memory via a specially crafted file. Successful exploitation may allow execution of arbitrary code. Autonomy KeyView versions 10.4 and 10.9 are affected.

Secunia Research has discovered a vulnerability in Autonomy KeyView, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused by a boundary error the WordPerfect 5.x reader (wosr.dll) when parsing data blocks and can be exploited to cause a heap-based buffer overflow via a specially crafted file. Successful exploitation may allow execution of arbitrary code. Autonomy KeyView versions 10.4 and 10.9 are affected.

Debian Linux Security Advisory 2075-1 - Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications.

Mandriva Linux Security Advisory 2010-140 - This is a maintenance and security update that upgrades php to 5.3.3 for 2010.0/2010.1. Rewrote var_export() to use smart_str rather than output buffering, prevents data disclosure if a fatal error occurs. Fixed a possible resource destruction issues in shm_put_var(). Fixed a possible information leak because of interruption of XOR operator. Fixed a possible memory corruption because of unexpected call-time pass by reference and following memory clobbering through callbacks. Fixed a possible memory corruption in ArrayObject::uasort(). Fixed a possible memory corruption in parse_str(). Fixed a possible memory corruption in pack(). Fixed a possible memory corruption in substr_replace(). Fixed a possible memory corruption in addcslashes(). Fixed a possible stack exhaustion inside fnmatch(). Fixed a possible dechunking filter buffer overflow. Fixed a possible arbitrary memory access inside sqlite extension. Fixed string format validation inside phar extension. Fixed handling of session variable serialization on certain prefix characters. Fixed a NULL pointer dereference when processing invalid XML-RPC requests. Fixed SplObjectStorage unserialization problems. Fixed possible buffer overflows in mysqlnd_list_fields, mysqlnd_change_user. Fixed possible buffer overflows when handling error packets in mysqlnd. Additionally some of the third party extensions and required dependencies has been upgraded and/or rebuilt for the new php version.

Ubuntu Security Notice 930-6 - USN-957-1 fixed vulnerabilities in Firefox and Xulrunner. Daniel Holbert discovered that the fix for CVE-2010-1214 introduced a regression which did not properly initialize a plugin pointer. If a user were tricked into viewing a malicious site, a remote attacker could use this to crash the browser or run arbitrary code as the user invoking the program. This update fixes the problem.

Likewise Security Advisory - A logic flaw has been found in the pam_lsass library from Likewise Open that, when run under the context of a root service (e.g. sshd, gdm, etc.), will allow any user to logon as a lsassd local-provider account (e.g. MACHINE\\Administrator) if the account's password is marked as expired.

The Mac OS X WebDAV kernel extension is vulnerable to a denial of service issue that allows a local unprivileged user to trigger a kernel panic due to a memory overallocation.

Ubuntu Security Notice 930-5 - USN-930-4 fixed vulnerabilities in Firefox and Xulrunner on Ubuntu 9.04 and 9.10. This update provides updated packages for use with Firefox 3.6 and Xulrunner 1.9.2. It was discovered that Firefox could be made to access freed memory. A flaw was discovered in the way plugin instances interacted. An integer overflow was discovered in Firefox. Martin Barbella discovered an integer overflow in an XSLT node sorting routine. Michal Zalewski discovered that the focus behavior of Firefox could be subverted. Ilja van Sprundel discovered that the 'Content-Disposition: attachment' HTTP header was ignored when 'Content-Type: multipart' was also present.

Ubuntu Security Notice 927-8 - USN-927-1 fixed vulnerabilities in NSS. This update provides the Thunderbird update to use the new NSS. Original advisory details: Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3 protocols. If an attacker could perform a man in the middle attack at the start of a TLS connection, the attacker could inject arbitrary content at the beginning of the user's session. This update adds support for the new new renegotiation extension and will use it when the server supports it.

Ubuntu Security Notice 927-7 - USN-927-4 fixed vulnerabilities in NSS. This update provides the NSPR needed to use the new NSS. Original advisory details: Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3 protocols. If an attacker could perform a man in the middle attack at the start of a TLS connection, the attacker could inject arbitrary content at the beginning of the user's session. This update adds support for the new new renegotiation extension and will use it when the server supports it.

Zero Day Initiative Advisory 10-137 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard OpenView Network Node Manager. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ov.dll module which is loaded by the webappmon.exe CGI program. This DLL defines a function execvp_nc which unsafely concatenates a controllable command string into a statically allocated stack buffer. By supplying overly large values to variables passed through an HTTP request a strcat_new can be made to overflow this buffer. An attacker can leverage this to execute arbitrary code under the context of the user running the webserver.
