Package : libxcursor
CVE ID : CVE-2017-16612
Debian Bug : 883792

It was discovered that libXcursor, a X cursor management library, is
prone to several heap overflows when parsing malicious files. An
attacker can take advantage of these flaws for arbitrary code execution,
if a user is tricked into processing a specially crafted cursor file.

For the oldstable distribution (jessie), these problems have been fixed
in version 1:1.1.14-1+deb8u1.

For the stable distribution (stretch), these problems have been fixed in
version 1:1.1.14-1+deb9u1.

We recommend that you upgrade your libxcursor packages.

For the detailed security status of libxcursor please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/libxcursor
