DCTStream.cc in Poppler before 0.13.3 allows remote attackers to cause a denial of service (crash) via a crafted PDF file.

The openTempFile function in goo/gfile.cc in Xpdf and Poppler 0.24.3 and earlier, when running on a system other than Unix, allows local users to overwrite arbitrary files via a symlink attack on temporary files with predictable names.

The JBIG2Stream::readSegments method in JBIG2Stream.cc in Poppler before 0.24.5 does not use the correct specifier within a format string, which allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted PDF file.

Format string vulnerability in the extractPages function in utils/pdfseparate.cc in poppler before 0.24.3 allows remote attackers to cause a denial of service (crash) via format string specifiers in a destination filename.

Stack-based buffer overflow in the extractPages function in utils/pdfseparate.cc in poppler before 0.24.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a source filename.

poppler/Stream.cc in poppler before 0.22.1 allows context-dependent attackers to have an unspecified impact via vectors that trigger a read of uninitialized memory by the CCITTFaxStream::lookChar function.

splash/Splash.cc in poppler before 0.22.1 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to the (1) Splash::arbitraryTransformMask, (2) Splash::blitMask, and (3) Splash::scaleMaskYuXu functions.

poppler before 0.22.1 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors that trigger an "invalid memory access" in (1) splash/Splash.cc, (2) poppler/Function.cc, and (3) poppler/Stream.cc.
