Stack-buffer overflow in GfxState.cc :
A stack-based buffer overflow was found in the poppler library. An attacker could create a malicious PDF file that would cause applications that use poppler (such as Evince) to crash, or potentially execute arbitrary code when opened. (CVE-2017-9775)
Integer overflow in JBIG2Stream.cc :
An integer overflow leading to heap-based buffer overflow was found in the poppler library. An attacker could create a malicious PDF file that would cause applications that use poppler (such as Evince) to crash, or potentially execute arbitrary code when opened.
