CVE-2026-102620
LowCVSS 3.3Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
A vulnerability was found in Poppler versions 26.06.0, 26.07.0 and 26.08.0 in the function FoFiTrueType::cvtSfnts of file fofi/FoFiTrueType.cc, causing an integer overflow. The attack can only be executed locally. The exploit has been publicly disclosed and may be utilized.
Risk Assessment
A local attacker could exploit the integer overflow to disrupt or potentially cause unintended operations in the document-processing process. Since the exploit is publicly known, the risk increases in environments where untrusted files are processed by applications using Poppler.
Recommendation
Install the available patch (245d3c6823377755f2c1d5fdddd010279c6ed94d) as soon as possible or upgrade Poppler to a version containing the fix. Until the patch is applied, limit processing of untrusted documents.
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.
