A flaw was found in libvirt, where it leaked a file descriptor for `/dev/mapper/control` into the QEMU process. This file descriptor allows for privileged operations to happen against the device-mapper on the host. This flaw allows a malicious guest user or process to perform operations outside of their standard permissions, potentially causing serious damage to the host operating system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
The DNS packet parser in YADIFA before 2.2.6 does not check for the presence of infinite pointer loops, and thus it is possible to force it to enter an infinite loop. This can cause high CPU usage and makes the server unresponsive.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.
The ContentProvider in the Canon PRINT jp.co.canon.bsd.ad.pixmaprint 2.5.5 application for Android does not properly restrict canon.ij.printer.capability.data data access. This allows an attacker's malicious application to obtain sensitive information including factory passwords for the administrator web interface and WPA2-PSK key.
