Description Arvid Requate

2017-09-08 10:30:28 CEST

Upstream Debian package version 2.1.0-5+deb8u10 fixes

* The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information. (CVE-2017-7890)

Upstream Debian package version 2.1.0-5+deb8u11 fixes

* Denial of service or potential execution of arbitrary code if a specially crafted file is processed due to double free vulnerability in the gdImagePngPtr function (CVE-2017-6362)
