A malicious or malformed DNS packet without a payload can cause an out-of-bounds read, resulting in a crash (denial of service) or an incorrect computation.
A flaw was found in Avahi-daemon, which relies on fixed source ports for wide-area DNS queries. This issue simplifies attacks where malicious DNS responses are injected.
The sequence of packets received by a Networking server are not correctly checked.
An attacker could exploit this vulnerability to send specially crafted messages to force the application to stop.
On affected platforms running Arista EOS with 802.1X configured, certain conditions may occur where a dynamic ACL is received from the AAA server resulting in only the first line of the ACL being inst
