Distribution: Fedora
Plattformen: Fedora 25

Applikationen: gd


Name        : gd
Product : Fedora 25
Version : 2.2.4
Release : 1.fc25
URL : http://libgd.github.io/
Summary : A graphics library for quick creation of PNG or JPEG images
Description :
The gd graphics library allows your code to quickly draw images
complete with lines, arcs, text, multiple colors, cut and paste from
other images, and flood fills, and to write out the result as a PNG or
JPEG file. This is particularly useful in Web applications, where PNG
and JPEG are two of the formats accepted for inline images by most
browsers. Note that gd is not a paint program.

in gd_interpolation.c - DOS vulnerability in gdImageCreateFromGd2Ctx() ###
Fixed - Fix #354: Signed Integer Overflow gd_io.c - Fix #340: System frozen -
Fix OOB reads of the TGA decompression buffer - Fix DOS vulnerability in
gdImageCreateFromGd2Ctx() - Fix potential unsigned underflow - Fix double-free
in gdImageWebPtr() - Fix invalid read in gdImageCreateFromTiffPtr() - Fix OOB
reads of the TGA decompression buffer - Fix #68: gif: buffer underflow reported
by AddressSanitizer - Avoid potentially dangerous signed to unsigned conversion
- Fix #304: test suite failure in gif/bug00006 [2.2.3] - Fix #329:
GD_BILINEAR_FIXED gdImageScale() can cause black border - Fix #330: Integer
overflow in gdImageScaleBilinearPalette() - Fix 321: Null pointer dereferences

quantization documentation - Fix #309: gdImageGd2() writes wrong chunk sizes on
boundaries - Fix #307: GD_QUANT_NEUQUANT fails to unset trueColor flag - Fix
#300: gdImageClone() assigns res_y = res_x - Fix #299: Regression regarding
gdImageRectangle() with gdImageSetThickness() - Replace GNU old-style field
designators with C89 compatible initializers - Fix #297: gdImageCrop() converts
palette image to truecolor image - Fix #290: TGA RLE decoding is broken - Fix
unnecessary non NULL checks - Fix #289: Passing unrecognized formats to
gdImageGd2 results in corrupted files - Fix #280: gdImageWebpEx()
parameter is a misnomer - Publish all gdImageCreateFromWebp*() functions and
gdImageWebpCtx() - Fix issue #276: Sometimes pixels are missing when storing
images as BMPs - Fix issue #275: gdImageBmpCtx() may segfault for non-seekable
contexts - Fix copy&paste error in gdImageScaleBicubicFixed() ### Added -
