Synopsis

The remote Debian host is missing a security update.

Description

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.

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected slirp package.
