Glyphandcog : Security Vulnerabilities, CVEs, (Overflow)

Xpdf prior to 4.04 lacked an integer overflow check in JPXStream.cc.

In Xpdf prior to 4.04, the DCT (JPEG) decoder was incorrectly allowing the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc.

xpdfreader 4.03 is vulnerable to Buffer Overflow.

An issue was discovered in Xpdf 4.01.01. There is an integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the "multiple bytes per line" case.

An issue was discovered in Xpdf 4.01.01. There is an Integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the "one byte per line" case.

In Xpdf 4.01.01, a heap-based buffer overflow could be triggered in DCTStream::decodeImage() in Stream.cc when writing to frameBuf memory. It can, for example, be triggered by sending a crafted PDF document to the pdftotext tool. It allows an attacker to use a crafted pdf file to cause Denial of Service, an information leak, or possibly unspecified other impact.

There is an Invalid memory access in gAtomicIncrement() located at GMutex.h in Xpdf 4.01. It can be triggered by sending a crafted pdf file to (for example) the pdftops binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.

Off-by-one error in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a different vulnerability than CVE-2011-0764.

t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, reads from invalid memory locations, which allows remote attackers to cause a denial of service (application crash) via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764.

Integer overflow in the ImageStream::ImageStream function in Stream.cc in Xpdf before 3.02pl4 and Poppler before 0.12.1, as used in GPdf, kdegraphics KPDF, and CUPS pdftops, allows remote attackers to cause a denial of service (application crash) via a crafted PDF document that triggers a NULL pointer dereference or buffer over-read.

Integer overflow in the ObjectStream::ObjectStream function in XRef.cc in Xpdf 3.x before 3.02pl4 and Poppler before 0.12.1, as used in GPdf, kdegraphics KPDF, CUPS pdftops, and teTeX, might allow remote attackers to execute arbitrary code via a crafted PDF document that triggers a heap-based buffer overflow.

Integer overflow in the PSOutputDev::doImageL1Sep function in Xpdf before 3.02pl4, and Poppler 0.x, as used in kdegraphics KPDF, might allow remote attackers to execute arbitrary code via a crafted PDF document that triggers a heap-based buffer overflow.

The Splash::drawImage function in Splash.cc in Xpdf 2.x and 3.x before 3.02pl4, and Poppler 0.x, as used in GPdf and kdegraphics KPDF, does not properly allocate memory, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF document that triggers a NULL pointer dereference or a heap-based buffer overflow.

Integer overflow in the SplashBitmap::SplashBitmap function in Xpdf 3.x before 3.02pl4 and Poppler before 0.12.1 might allow remote attackers to execute arbitrary code via a crafted PDF document that triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2009-1188.

Multiple buffer overflows in the JBIG2 MMR decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allow remote attackers to execute arbitrary code via a crafted PDF file.

Integer overflow in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to execute arbitrary code via a crafted PDF file.

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (crash) via a crafted PDF file that triggers an out-of-bounds read.

Heap-based buffer overflow in Xpdf 3.02pl2 and earlier, CUPS 1.3.9, and probably other products, allows remote attackers to execute arbitrary code via a PDF file with crafted JBIG2 symbol dictionary segments.

Integer overflow in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, as used in Poppler and other products, when running on Mac OS X, has unspecified impact, related to "g*allocn."

Multiple buffer overflows in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, and other products allow remote attackers to cause a denial of service (crash) via a crafted PDF file, related to (1) JBIG2SymbolDict::setBitmap and (2) JBIG2Stream::readSymbolDictSeg.
