Debian Security Advisory DSA-4844-1 [email protected]

Package : dnsmasq
CVE ID : CVE-2020-25681 CVE-2020-25682 CVE-2020-25683 CVE-2020-25684
CVE-2020-25685 CVE-2020-25686 CVE-2020-25687
Moshe Kol and Shlomi Oberman of JSOF discovered several
vulnerabilities in dnsmasq, a small caching DNS proxy and DHCP/TFTP
server. They could result in denial of service, cache poisoning or the
execution of arbitrary code.
For the stable distribution (buster), these problems have been fixed in
version 2.80-1+deb10u1.
We recommend that you upgrade your dnsmasq packages.
