Vulnerabilities

Infinite loop in Xpdf 4.06 and earlier, due to incorrect validation of progression order field in JPEG 2000 image.

Divide-by-zero in Xpdf 4.06 (and earlier), when a glyph in a Type 3 font has a zero height.

Out-of-bounds array write in Xpdf 4.06 and earlier, due to incorrect validation of the "N" field in ICCBased color spaces.

In Xpdf 4.05 (and earlier), a PDF object loop in a CMap, via the "UseCMap" entry, leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by an invalid VerticesPerRow value in a PDF shading dictionary.

Out-of-bounds array write in Xpdf 4.05 and earlier, due to incorrect integer overflow checking in the PostScript function interpreter code.

In Xpdf 4.05 (and earlier), invalid header info in a DCT (JPEG) stream can lead to an uninitialized variable in the DCT decoder.

In Xpdf 4.05 (and earlier), very large coordinates in a page box can cause an integer overflow and divide-by-zero.

In Xpdf 4.05 (and earlier), a PDF object loop in a pattern resource leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, due to missing object type check in AcroForm field reference.

In Xpdf 4.05 (and earlier), a PDF object loop in the PDF resources leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by an invalid character code in a Type 1 font.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by long Unicode sequence in ActualText.

In Xpdf 4.05 (and earlier), a PDF object loop in the attachments leads to infinite recursion and a stack overflow.

In Xpdf 4.05 (and earlier), a PDF object loop in an object stream leads to infinite recursion and a stack overflow.

Out-of-bounds array write in Xpdf 4.05 and earlier, triggered by negative object number in indirect reference in the input PDF file.

Xpdf 4.04 will deadlock on a PDF object stream whose "Length" field is itself in another object stream.

An excessively large PDF page size (found in fuzz testing, unlikely in normal PDF files) can result in a divide-by-zero in Xpdf's text extraction code.

In Xpdf 4.04 (and earlier), a PDF object loop in the embedded file tree leads to infinite recursion and a stack overflow.

In Xpdf 4.04 (and earlier), a PDF object loop in the page label tree leads to infinite recursion and a stack overflow.

In Xpdf 4.04 (and earlier), a bad color space object in the input PDF file can cause a divide-by-zero.

xpdf allows remote attackers to cause a denial of service (NULL pointer dereference and crash) in the way it processes JBIG2 PDF stream objects.

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allow…

Heap-based buffer overflow in the CCITTFaxStream::lookChar method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a PDF file that contains a crafted CCITTFaxDecode filter.

Integer overflow in the DCTStream::reset method in xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers to execute arbitrary code via a crafted PDF file, resulting in a heap-based buffer overflow.
