CVE-2026-12600
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
Denial-of-service (DoS) vulnerability in the internal JPEG2000 (JPX) decoding implementation of the Poppler fork developed by Innodata Labs. When an application processes an untrusted PDF file containing specially crafted JPXDecode images, a remote attacker can cause uncontrolled memory consumption. The flaw occurs in the JPXStream::readCodestream() function, where values controlled from the SIZ segment (such as img.nComps) are used for the memory allocation of tiles and components without adequate validation. This allows an attacker to force excessive memory allocation and cause a resource exhaustion, ultimately causing the pdftoppm process to terminate due to out-of-memory (OOM) conditions.
Risk Assessment
An attacker can cause the PDF processing application to crash, potentially leading to service disruption and system unavailability.
Recommendation
Update Poppler to a version containing a fix for this vulnerability and restrict processing of untrusted PDF files.
Other vulnerabilities in Poppler
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-2017-14976High
The FoFiType1C::convertToType0 function in Poppler 0.59.0 has a heap-based buffer over-read vulnerability when encountering an out-of-bounds font dictionary index. This can be exploited by 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.
