Fedora 26: leptonica Security Update
Summary
The library supports many operations that are useful on
* Document images
* Natural images
Fundamental image processing and image analysis operations
* Rasterop (aka bitblt)
* Affine transforms (scaling, translation, rotation, shear)
on images of arbitrary pixel depth
* Projective and bi-linear transforms
* Binary and gray scale morphology, rank order filters, and
convolution
* Seed-fill and connected components
* Image transformations with changes in pixel depth, both at
the same scale and with scale change
* Pixelwise masking, blending, enhancement, arithmetic ops,
etc.
This update fixes CVE-2017-18196. ---- This update backports security fixes
for CVE-2018-3836, CVE-2018-7186 and CVE-2018-7247.
