Version        : 1:1.0.17-8+deb9u1
CVE ID         : CVE-2020-7039 CVE-2020-8608

Two issues have been found in slirp, a SLIP/PPP emulator using a dial up 
shell account.


     Due to mismanagement of memory, a heap-based buffer overflow or
     other out-of-bounds access might happen, which can lead to a DoS
     or potential execute arbitrary code.


     Prevent a buffer overflow vulnerability due to incorrect usage
     of return values from snprintf.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your slirp packages.
