A flaw was found in HTTP/2. Using frames with an empty payload, a flood could occur that results in excessive CPU usage and starvation of other clients. The highest threat from this vulnerability is to system availability.
A flaw was found in HTTP/2. An attacker, using PRIORITY frames to flood the system, could cause excessive CPU usage and starvation of other clients. The largest threat from this vulnerability is to system availability.
A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.
A flaw was found in HTTP/2. Using SETTINGS frames and queuing of SETTINGS ACK frames, a flood could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.
A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a denial of service. The highest threat from this vulnerability is to system availability.
A heap-based buffer overflow was found in the way sudo parses command line arguments.
As per the researcher this vulnerability:
- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);
- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.
This could lead to privilege escalation.
