KOffice Security Advisory: KOffice olefilters integer overflow Original Release Date: 2006-12-04 URL: http://www.kde.org/info/security/advisory-20061204-1.txt
KOffice 1.4.x and 1.6.0. 1.5.x releases are unaffected as well as 1.6.1 or newer.
The OLE import filter, which is used in KPresenter to open Microsoft Powerpoint files is vulnerable to an integer overflow problem that can be exploited to expose an heap memory overflow. This issue was reported by Kees Cook from Ubuntu security.
A maliciously crafted file can cause to execute arbitrary code.
Source code patches have been made available which fix these vulnerabilities. Contact your OS vendor / binary package provider fo information about how to obtain updated binary packages.
A patch for KOffice 1.4.0 - KOffice 1.6.0 is available from ftp://ftp.kde.org/pub/kde/security_patches : 20dff20ccd2e184f1874aa60d85f4380 post-koffice-1.6.0.diff
