KDE Security Advisory: kpdf/xpdf multiple integer overflows Original Release Date: 2005-12-07 URL: http://www.kde.org/info/security/advisory-20051207-1.txt 0. References CAN-2005-3191 CAN-2005-3192 CAN-2005-3193 1. Systems affected: KDE 3.2.0 up to including KDE 3.5.0 KOffice 1.3.0 up to including KOffice 1.4.2 2. Overview: kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains multiple integer overflow vulnerabilities that allow specially crafted pdf files, when opened, to overflow a heap allocated buffer and execute arbitrary code. 3. Impact: Remotely supplied pdf files can be used to execute arbitrary code on the client machine. 4. Solution: Source code patches have been made available which fix these vulnerabilities. Contact your OS vendor / binary package provider for information about how to obtain updated binary packages. 5. Patch: Patch for KDE 3.5.0 is available from ftp://ftp.kde.org/pub/kde/security_patches : 04d1a115cca0deacbfca5c172bb9f4db post-3.5.0-kdegraphics-CAN-2005-3193.diff Patch for KDE 3.4.3 is available from ftp://ftp.kde.org/pub/kde/security_patches : b9787ff17e3e7eccee9ff23edcdca2c1 post-3.4.3-kdegraphics-CAN-2005-3193.diff Patch for KDE 3.3.2 is available from ftp://ftp.kde.org/pub/kde/security_patches : 8e0b2db76bc419b444f8308b3d8127b9 post-3.3.2-kdegraphics-CAN-2005-3193.diff Patch for KDE 3.2.3 is available from ftp://ftp.kde.org/pub/kde/security_patches : 75c90ff2998ff7b4c1b66fbf85d351f1 post-3.2.3-kdegraphics-CAN-2005-3193.diff Patch for KOffice 1.3.0 and newer is available from ftp://ftp.kde.org/pub/kde/security_patches : e663d0b1b6c32c3fb99c85834ae7b17b post-1.3-koffice-CAN-2005-3193.diff -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQBDl1BXvsXr+iuy1UoRAhYxAKCrRpvP/yxFmk1cHj3xTswt4EWw/QCeNRnN sXKlUy7WElj2JBWc+e7jvY0= =yMzI -----END PGP SIGNATURE-----
