HTTP/2 contains a rapid reset vulnerability that allows for a distributed denial-of-service attack (DDoS).
- 5.5Linux Kernel Race Condition Vulnerability
Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings.
- 9.8GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute code.
- 9.8GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute code.
Which Big-IP Webaccelerator flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
