Description

It was discovered that WebKit did not properly handle certain SVGPathList data structures. If a user were tricked into viewing a malicious website, an attacker could exploit this to execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0945)

Several flaws were discovered in the WebKit browser and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1687, CVE-2009-1690, CVE-2009-1698, CVE-2009-1711, CVE-2009-1725)

It was discovered that WebKit did not prevent the loading of local Java applets. If a user were tricked into viewing a malicious website, an attacker could exploit this to execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1712).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
