Synopsis ========
An integer overflow in koffice-libs allows for a Denial of Service and possibly the execution of arbitrary code when viewing malicious PowerPoint files.
Background ==========
KOffice is an integrated office suite for KDE. koffice-libs is a package containing shared librares used by KOffice programs.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-office/koffice-libs < 1.5.0 >= 1.5.0
Description ===========
Kees Cook of Ubuntu discovered that 'KLaola::readBigBlockDepot()' in klaola.cc fills 'num_of_bbd_blocks' while reading a .ppt (PowerPoint) file without proper sanitizing, resulting in an integer overflow subsequently overwriting the heap with parts of the file being read.
Impact ======
By enticing a user to open a specially crafted PowerPoint file, an attacker could crash the application and possibly execute arbitrary code with the rights of the user running KOffice.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All koffice-libs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/koffice-libs-1.5.0"
