Synopsis
The remote Debian host is missing a security-related update.
Description
Several vulnerabilities have been discovered in qt4-x11, a cross-platform C++ application framework. The Common Vulnerabilities and Exposures project identifies the following problems :
- CVE-2009-0945 Array index error in the insertItemBefore method in WebKit, as used in qt4-x11, allows remote attackers to execute arbitrary code.
- CVE-2009-1687 The JavaScript garbage collector in WebKit, as used in qt4-x11 does not properly handle allocation failures, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document that triggers write access to an 'offset of a NULL pointer.
- CVE-2009-1690 Use-after-free vulnerability in WebKit, as used in qt4-x11, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by setting an unspecified property of an HTML tag that causes child elements to be freed and later accessed when an HTML error occurs.
- CVE-2009-1698 WebKit in qt4-x11 does not initialize a pointer during handling of a Cascading Style Sheets (CSS) attr function call with a large numerical argument, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.
- CVE-2009-1699 The XSL stylesheet implementation in WebKit, as used in qt4-x11 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD.
- CVE-2009-1711 WebKit in qt4-x11 does not properly initialize memory for Attr DOM objects, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document.
- CVE-2009-1712 WebKit in qt4-x11 does not prevent remote loading of local Java applets, which allows remote attackers to execute arbitrary code, gain privileges, or obtain sensitive information via an APPLET or OBJECT element.
- CVE-2009-1713 The XSLT functionality in WebKit, as used in qt4-x11 does not properly implement the document function, which allows remote attackers to read arbitrary local files and files from different security zones.
- CVE-2009-1725 WebKit in qt4-x11 does not properly handle numeric character references, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.
- CVE-2009-2700 qt4-x11 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.
The oldstable distribution (etch) is not affected by these problems.
Solution
Upgrade the qt4-x11 packages.
For the stable distribution (lenny), these problems have been fixed in version 4.4.3-1+lenny1.
