Description

According to the version of the netpbm packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • The netpbm package contains a library of functions which support programs for handling various graphics file formats, including .pbm (portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps),.ppm (portable pixmaps) and others.Security Fix(es):The pm_mallocarray2 function in lib/util/mallocvar.c in Netpbm through 10.81.03 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, as demonstrated by pbmmask.(CVE-2018-8975)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
