Different flaws have been found in leptonlib, an image processing
Leptonica did not limit the number of characters in a %s format
argument to fscanf or sscanf, that made it possible to remote
attackers to cause a denial of service (stack-based buffer overflow)
or possibly have unspecified other impact via a long string.
The gplotMakeOutput function allowed command injection via a
$(command) approach in the gplot rootname argument. This issue
existed because of an incomplete fix for CVE-2018-3836.
For Debian 7 "Wheezy", these problems have been fixed in version
We recommend that you upgrade your leptonlib packages.
