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.
2) Memory leak (CVE-ID: CVE-2018-18897)

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
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.
