========================================================================== Ubuntu Security Notice USN-4632-1 November 12, 2020
slirp vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
slirp could be made to crash if it received specially crafted input.
Software Description: - slirp: SLIP/PPP emulator using a dial up shell account
Details:
It was discovered that the SLiRP networking implementation of the QEMU emulator did not properly manage memory under certain circumstances. An attacker could use this to cause a heap-based buffer overflow or other out- of-bounds access, which can lead to a denial of service (application crash) or potentially execute arbitrary code. (CVE-2020-7039)
It was discovered that the SLiRP networking implementation of the QEMU emulator misuses snprintf return values. An attacker could use this to cause a denial of service (application crash) or potentially execute arbitrary code. (CVE-2020-8608)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: slirp 1:1.0.17-8ubuntu18.04.1
Ubuntu 16.04 LTS: slirp 1:1.0.17-8ubuntu16.04.1
In general, a standard system update will make all the necessary changes.
