More information:

Different flaws have been found in leptonlib, an image processing library.

• CVE-2018-7186

  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.

• CVE-2018-7440

  The gplotMakeOutput function allowed command injection via a 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 1.69-3.1+deb7u2.

We recommend that you upgrade your leptonlib packages.
