Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Memory leak (CVE-ID: CVE-2018-18897)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo. A remote attacker can execute the pdftocairo command with a PDF file that submits malicious input, trigger memory leak and cause the service to crash.
2) NULL pointer dereference (CVE-ID: CVE-2018-20481)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when XRef::getEntry in XRef.cc mishandles unallocated XRef entries. A remote attacker can trigger denial of service conditions via a specially crafted PDF document, when XRefEntry::setFlag in XRef.h is called from Parser::makeStream in Parser.cc.
3) Reachable Assertion (CVE-ID: CVE-2018-20551)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to reachable Object::getString assertion due to construction of invalid rich media annotation assets in the AnnotRichMedia class in Annot.c. A remote attacker can cause a denial of service.
4) Reachable Assertion (CVE-ID: CVE-2018-20650)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in FileSpec.cc) in pdfdetach. A remote attacker can cause a denial of service.
5) Input validation error (CVE-ID: CVE-2018-20662)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a wrong return value from PDFDoc::setup when an xref data structure is mishandled during extractPDFSubtype processing. A remote attacker can trick the victim into opening a specially crafter PDF file cause application crash by Object.h SIGABRT.
6) Heap-based buffer over-read (CVE-ID: CVE-2019-7310)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an integer signedness error in the XRef::getEntry function in XRef.cc. A remote attacker can trick the victim into processing a specially crafted PDF document, as demonstrated by pdftocairo, trigger heap-based buffer over-read and perform a denial of service.
7) Heap-based buffer overflow (CVE-ID: CVE-2019-9200)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing PDF files in ImageStream::getLine() function in Stream.cc. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Out-of-bounds read (CVE-ID: CVE-2019-9631)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the CairoRescaleBox.cc downsample_row_box_filter function. A remote attacker can perform a denial of service attack.
9) Resource exhaustion (CVE-ID: CVE-2019-9903)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect processing of dict marking in PDFDoc::markObject() function in PDFDoc.cc file when processing PDF files. A remote attacker can pass specially crafted PDF file to the affected software that invokes pdfunite binary, trigger resource exhaustion and perform a denial of service (DoS) attack.
10) Integer overflow (CVE-ID: CVE-2019-9959)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the "JPXStream::init" function, caused by a failure to bounds-check user-supplied data before copying it to an undersized memory buffer. A remote attacker can supply crafted data to the system, trigger integer overflow and cause a denial of service condition on the targeted system.
11) Out-of-bounds read (CVE-ID: CVE-2019-10871)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the function PSOutputDev::checkPageSlice in PSOutputDev.cc. A remote attacker can perform a denial of service attack.
12) Out-of-bounds read (CVE-ID: CVE-2019-12293)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in JPXStream::init() function in JPEG2000Stream.cc via data with inconsistent heights or widths. A remote attacker can perform a denial of service attack.
