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

CVE-2020-7039

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.

CVE-2020-8608

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
1:1.0.17-8+deb9u1.

We recommend that you upgrade your slirp packages.
