GLSA-200711-22 : Poppler, KDE: User-assisted execution of arbitrary code

Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200711-22
(Poppler, KDE: User-assisted execution of arbitrary code)

Alin Rad Pop (Secunia Research) discovered several vulnerabilities in
the 'Stream.cc' file of Xpdf: An integer overflow in the
DCTStream::reset() method and a boundary error in the
CCITTFaxStream::lookChar() method, both leading to heap-based buffer
overflows (CVE-2007-5392, CVE-2007-5393). He also discovered a boundary
checking error in the DCTStream::readProgressiveDataUnit() method
causing memory corruption (CVE-2007-4352). Note: Gentoo's version of
Xpdf is patched to use the Poppler library, so the update to Poppler
will also fix Xpdf.

Impact :

By enticing a user to view or process a specially crafted PDF file with
KWord or KPDF or a Poppler-based program such as Gentoo's viewers Xpdf,
ePDFView, and Evince or the CUPS printing system, a remote attacker
could cause an overflow, potentially resulting in the execution of
arbitrary code with the privileges of the user running the application.

Workaround :

There is no known workaround at this time.

Solution :

All Poppler users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/poppler-0.6.1-r1'
All KPDF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=kde-base/kpdf-3.5.7-r3'
All KDE Graphics Libraries users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=kde-base/kdegraphics-3.5.7-r3'
All KWord users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-office/kword-1.6.3-r2'
All KOffice users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-office/koffice-1.6.3-r2'
