The remote NewStart CGSL host, running version MAIN 6.02, has poppler packages installed that are affected by multiple vulnerabilities:
An issue was discovered in Poppler through 0.78.0. There is a divide-by-zero error in the function SplashOutputDev::tilingPatternFill at SplashOutputDev.cc. (CVE-2019-14494)
A flaw was found in Poppler in the way certain PDF files were converted into HTML. A remote attacker could exploit this flaw by providing a malicious PDF file that, when processed by the ‘pdftohtml’ program, would crash the application causing a denial of service. (CVE-2020-27778)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
