net-imap vulnerable to denial of service via high iteration count for `SCRAM-*` authentication
Summary When authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational denial-of-service attack on the client process by sending a big iteration count value. Details A hostile IMAP server can send an arbitrarily large PBKDF2 iteration count in the...
CVE-2026-36365
An issue in Lymphatus caesium-image-compressor All versions up to and including commit 02da2c6 allows a local attacker to execute arbitrary code via the shutdownMachine and putMachineToSleep functions in PostCompressionActions.cpp...
Zero Day Attacks: Novel Behaviour or Novel Vulnerability?
Zero-day attacks pose severe cybersecurity risks due to their high success rates and stealth. Because signature-based approaches struggle to detect such attacks, building Intrusion Detection Systems IDSs for detecting zero-day attacks is essential. We contend that for an IDS to be effective it mu...
