Firejail Local Elevation of Privilege Vulnerability

Firejail is a SUID program designed to reduce the risk of security violations by restricting the runtime environment of untrusted applications through the use of Linux namespaces and seccomp-bpf. Firejail suffers from a local elevation of privilege vulnerability. An attacker could exploit this...

PCAUSA Rawether for Windows local privilege escalation

Overview PCAUSA's Rawether framework does not properly validate BPF data, allowing a crafted malicious BPF program to perform operations on memory outside of its typical bounds on the driver's receipt of network packets. This vulnerability may be exploited to perform local privilege escalation on...
