Design/Logic Flaw

The unity-firefox-extension package could be tricked into dropping a C callback which was still in use, which Firefox would then free, causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was...

Regular Expression Denial of Service (ReDoS) in Jinja2

This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDOS vulnerability of the regex is mainly due to the sub-pattern a-zA-Z0-9.-+.a-zA-Z0-9.-+ This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiti...

kernel: ICMP rate limiting can be used for DNS poisoning attack

A flaw in the way reply ICMP packets are limited in the Linux kernel functionality was found that allows to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentialit...

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI and has a length up to the maximum length of a Netlink message.

Denial of Service in Page Error Handling

Requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack...
