Other vulnerabilities in Poppler 0.59.0
See all- CVE-2017-15565High
In Poppler 0.59.0, a NULL Pointer Dereference exists in the GfxImageColorMap::getGrayLine() function in GfxState.cc via a crafted PDF document.
- CVE-2017-14977High
The FoFiTrueType::getCFFBlock function in Poppler 0.59.0 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-2017-14975High
The FoFiType1C::convertToType0 function in Poppler 0.59.0 has a NULL pointer dereference vulnerability because a data structure is not initialized, allowing an attacker to launch a denial of service attack.
- CVE-2017-14929High
In Poppler 0.59.0, memory corruption occurs in a call to Object::dictLookup() in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opFill, Gfx::doPatternFill, Gfx::doTilingPatternFill, and Gfx::drawForm calls. This is a different vulnerability than CVE-2017-14519.
- CVE-2017-14617High
In Poppler 0.59.0, a floating point exception occurs in the ImageStream class in Stream.cc, which may lead to a potential attack when handling malicious PDF files.
- CVE-2017-14520High
In Poppler 0.59.0, a floating point exception occurs in Splash::scaleImageYuXd() in Splash.cc, which may lead to a potential attack when handling malicious PDF files.
- CVE-2017-14519High
In Poppler 0.59.0, memory corruption occurs in a call to Object::streamGetChar in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opShowText, and Gfx::doShowText calls (aka a Gfx.cc infinite loop).
- CVE-2017-14518High
In Poppler 0.59.0, a floating point exception exists in the isImageInterpolationRequired() function in Splash.cc via a crafted PDF document.
- CVE-2017-2820High
An exploitable integer overflow vulnerability exists in the JPEG 2000 image parsing functionality of Poppler 0.53.0. Opening a specially crafted PDF file can lead to an overflow, resulting in out of bounds memory overwrite on the heap and potential arbitrary code execution.
- CVE-2017-2818High
A heap overflow vulnerability exists in the image rendering functionality of Poppler 0.53.0. A specifically crafted PDF can cause an overly large number of color components during image rendering, resulting in heap corruption.
