Package        : libgc
Version        : 1:7.4.2-8+deb9u1
CVE ID         : CVE-2016-9427


libgc, a conservative garbage collector, is vulnerable to integer 
overflows in multiple places. In some cases, when asked to allocate a huge 
quantity of memory, instead of failing the request, it will return a 
pointer to a small amount of memory possibly tricking the application into 
a buffer overwrite.


For Debian 9 stretch, this problem has been fixed in version
1:7.4.2-8+deb9u1.

We recommend that you upgrade your libgc packages.
