Package : slirp 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 1:1.0.17-8+deb9u1.

We recommend that you upgrade your slirp packages.
