GHSA-M6XR-FVFG-5G64 Dasel: Denial of service in dasel selector lexer due to infinite loop on unterminated regex literal

Summary dasel's selector lexer enters a non-terminating loop when tokenizing an unterminated regex pattern such as r/abc. A 2-byte input r/ is sufficient to cause the tokenizer to consume 100% CPU on one core indefinitely. I confirmed the issue on v3.3.1 fba653c7f248aff10f2b89fca93929b64707dfc8 a...

GHSA-2MGW-7Q6P-8GRG FPDI: Memory Exhaustion and Endless Loop in FPDI leads to Denial of Service

Impact This is a significant Denial of Service DoS vulnerability. Any application that uses FPDI to process user-supplied PDF files is at risk. An attacker can upload a small, malicious PDF file that will cause the server-side script to crash due to memory exhaustion or a script time-out. Repeate...
