curl: CURLOPT_HSTS_CTRL disables shared HSTS without share guard — use-after-free and double-free

Hi all, CURLOPTHSTSCTRL set to a value without CURLHSTSENABLE unconditionally frees the easy's HSTS object — even when that object is shared via a CURLSH. The result is a use-after-free and a double-free on the shared 48-byte struct hsts block when the share or any other linked easy is later torn...

CVE-2026-44368 PyQuorum: Timing side‑channel in mul_mod

PyQuorum is a cryptographic library for secret sharing and key management. Prior to 0.2.1, the mulmod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand the exponent. An attacker who can measure the time of...
