Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2012-4513)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in khtml/imload/scaledimageplane.h in Konqueror in KDE 4.7.3. A remote attacker can perform a denial of service (crash) and possibly read memory via large canvas dimensions, which leads to an unexpected sign extension and a heap-based buffer over-read.


2) Resource management error (CVE-ID: CVE-2012-4515)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Use-after-free vulnerability in khtml/rendering/render_replaced.cpp in Konqueror in KDE 4.7.3, when the context menu is shown, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by accessing an iframe when it is being updated.
