Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-1000456)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to improper validation of boundaries in TextPool::addWord in freedesktop.org libpoppler. A remote attacker can trigger overflow in subsequent calculations and cause the service to crash.
2) NULL pointer derefenrece (CVE-ID: CVE-2017-14517)
The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.
The vulnerability exists due to an error in XRef::parseEntry() function in XRef.cc when processing PDF documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.
Successful exploitation of the vulnerability may allow an attacker to cause application crash.
3) Division by zero (CVE-ID: CVE-2017-14518)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a floating point exception in the isImageInterpolationRequired() function in Splash.cc via a specially crafted PDF document. A remote attacker can perform a denial of service (DoS) attack.
4) Division by zero (CVE-ID: CVE-2017-14520)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a floating point exception in Splash::scaleImageYuXd() in Splash.cc. A remote attacker can perform a denial of service (DoS) attack.
5) Improper input validation (CVE-ID: CVE-2017-14617)
The vulnerability allows a remote attacker to bypass security restrictions on the target system.
The vulnerability exists due to a floating point exception in the ImageStream class in Stream.cc. A remote attacker can supply specially crafted PDF files, bypass security restrictions and conduct further attacks.
6) NULL pointer derefenrece (CVE-ID: CVE-2017-14928)
The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.
The vulnerability exists due to an error in AnnotRichMedia::Configuration::Configuration in Annot.cc when processing PDF documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.
Successful exploitation of the vulnerability may allow an attacker to cause application crash.
7) NULL pointer derefenrece (CVE-ID: CVE-2017-14975)
The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.
The vulnerability exists due to an error in FoFiType1C::convertToType0 function in FoFiType1C.cc when processing documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.
Successful exploitation of the vulnerability may allow an attacker to cause application crash.
8) Heap-based buffer overflow (CVE-ID: CVE-2017-14976)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to boundary error in FoFiType1C::convertToType0 function in FoFiType1C.cc when processing fonts in documents. A remote unauthenticated attacker can create a specially crafted document and trigger application crash.
9) NULL pointer derefenrece (CVE-ID: CVE-2017-14977)
The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.
The vulnerability exists due to an error in FoFiTrueType::getCFFBlock function in FoFiTrueType.cc when processing documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.
Successful exploitation of the vulnerability may allow an attacker to cause application crash.
10) NULL pointer derefenrece (CVE-ID: CVE-2017-15565)
The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.
The vulnerability exists due to an error in GfxImageColorMap::getGrayLine() function in GfxState.cc when processing PDF documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.
Successful exploitation of the vulnerability may allow an attacker to cause application crash.
11) Buffer over-read (CVE-ID: CVE-2017-9865)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in The function GfxImageColorMap::getGray in GfxState.cc in Poppler 0.54.0. A remote attacker can perform a denial of service (stack-based buffer over-read and application crash) via a specially crafted PDF document, related to missing color-map validation in ImageOutputDev.cc.
