Description

Package : leptonlib Version : 1.69-3.1+deb7u2 CVE ID : CVE-2018-7186 CVE-2018-7440 Debian Bug : 890548 891932

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
$(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 1.69-3.1+deb7u2.

We recommend that you upgrade your leptonlib packages.
