CVE-2017-14976

The FoFiType1C::convertToType0 function in FoFiType1C.cc in Poppler 0.59.0 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.

In Poppler 0.59.0, a NULL Pointer Dereference exists in the SplashOutputDev::type3D0() function in SplashOutputDev.cc via a crafted PDF document. (CVE-2017-14927)

This update for poppler fixes the following issues:

These security issues were fixed:

• CVE-2017-14517: Prevent NULL Pointer dereference in the XRef::parseEntry() function via a crafted PDF document (bsc#1059066).
• CVE-2017-9865: Fixed a stack-based buffer overflow vulnerability in GfxState.cc that would have allowed attackers to facilitate a denial-of-service attack via specially crafted PDF documents. (bsc#1045939)
• CVE-2017-14518: Remedy a floating point exception in isImageInterpolationRequired() that could have been exploited using a specially crafted PDF document. (bsc#1059101)
• CVE-2017-14520: Remedy a floating point exception in Splash::scaleImageYuXd() that could have been exploited using a specially crafted PDF document. (bsc#1059155)
• CVE-2017-14617: Fixed a floating point exception in Stream.cc, which may lead to a potential attack when handling malicious PDF files. (bsc#1060220)
• CVE-2017-14928: Fixed a NULL Pointer dereference in AnnotRichMedia::Configuration::Configuration() in Annot.cc, which may lead to a potential attack when handling malicious PDF files. (bsc#1061092)
• CVE-2017-14975: Fixed a NULL pointer dereference vulnerability, that existed because a data structure in FoFiType1C.cc was not initialized, which allowed an attacker to launch a denial of service attack. (bsc#1061263)
