Package        : zlib
Version        : 1:1.2.8.dfsg-5+deb9u1
CVE ID         : CVE-2018-25032
Debian Bug     : 1008265

One security issue has been found in a compression library zlib.

Danilo Ramos discovered that incorrect memory handling in zlib's deflate
handling could result in denial of service or potentially the execution
of arbitrary code if specially crafted input is processed.

For Debian 9 stretch, this problem has been fixed in version
1:1.2.8.dfsg-5+deb9u1.

We recommend that you upgrade your zlib packages.

For the detailed security status of zlib please refer to
its security tracker page at:
