Several security issues have been discovered in kde4libs, core libraries for all KDE 4 applications. The Common Vulnerabilities and Exposures project identifies the following problems: It was discovered that there is a use-after-free flaw in handling certain DOM event handlers. This could lead to the execution of arbitrary code, when visiting a malicious website. It was discovered that there could ...

Dan Kaminsky discovered that properties inherent to the DNS protocol lead to practical DNS cache poisoning attacks. Among other things, successful attacks can lead to misdirected web traffic and email rerouting. This update changes Debian's dnsmasq packages to implement the recommended countermeasure: UDP query source port randomization. This change increases the size of the space from which an at ...

In DSA-1603-1, Debian released an update to the BIND 9 domain name server, which introduced UDP source port randomization to mitigate the threat of DNS cache poisoning attacks (identified by the Common Vulnerabilities and Exposures project as CVE-2008-1447). The fix, while correct, was incompatible with the version of SELinux Reference Policy shipped with Debian Etch, which did not permit a proces ...

Dan Kaminsky and Moxie Marlinspike discovered that kdelibs, core libraries from the official KDE release, does not properly handle a "\0" character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

Multiple weaknesses have been identified in PyDNS, a DNS client implementation for the Python language. Dan Kaminsky identified a practical vector of DNS response spoofing and cache poisoning, exploiting the limited entropy in a DNS transaction ID and lack of UDP source port randomization in many DNS implementations. Scott Kitterman noted that python-dns is vulnerable to this predictability, as it ...

Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications, such as the Iceweasel web browser. The Common Vulnerabilities and Exposures project identifies the following problems: Vladimir Vukicevic, Jesse Ruderman, Martijn Wargers, Daniel Banchero, David Keeler and Boris Zbarsky reported crashes in layout engine, which might allow the execution of ...

Two security issues have been discovered in kdegraphics, the graphics apps from the official KDE release. The Common Vulnerabilities and Exposures project identifies the following problems: It was discovered that the KSVG animation element implementation suffers from a null pointer dereference flaw, which could lead to the execution of arbitrary code. It was discovered that the KSVG animation elem ...

Bzip2 is a freely available, patent-free, high quality data compressor. Bzip2 compresses files to within 10 to 15 percent of the capabilities of the best techniques available. However, bzip2 has the added benefit of being approximately two times faster at compression and six times faster at decompression than those techniques. Bzip2 is not the fastest compression utility, but it does strike a bala ...
