Title:	Debian: Security Advisory (DLA-1177-1)
Summary:	The remote host is missing an update for the Debian 'poppler' package(s) announced via the DLA-1177-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'poppler' package(s) announced via the DLA-1177-1 advisory. Vulnerability Insight: It was discovered that poppler, a PDF rendering library, was affected by several denial-of-service (application crash), null pointer dereferences and heap-based buffer over-read bugs: CVE-2017-14975 The FoFiType1C::convertToType0 function in FoFiType1C.cc has a NULL pointer dereference vulnerability because a data structure is not initialized, which allows an attacker to launch a denial of service attack. CVE-2017-14976 The FoFiType1C::convertToType0 function in FoFiType1C.cc has a heap-based buffer over-read vulnerability if an out-of-bounds font dictionary index is encountered, which allows an attacker to launch a denial of service attack. CVE-2017-14977 The FoFiTrueType::getCFFBlock function in FoFiTrueType.cc has a NULL pointer dereference vulnerability due to lack of validation of a table pointer, which allows an attacker to launch a denial of service attack. CVE-2017-15565 NULL Pointer Dereference exists in the GfxImageColorMap::getGrayLine() function in GfxState.cc via a crafted PDF document. For Debian 7 Wheezy, these problems have been fixed in version 0.18.4-6+deb7u4. We recommend that you upgrade your poppler packages.
