Summary
slirp vulnerabilities
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)
