Updated

Out-of-Bounds Read vulnerability in the cookie date handling code of the libsoup HTTP library. The flaw is caused by improper bounds checking in the soupdatetimetostring() function when formatting crafted cookie expiration dates. An attacker can exploit this by sending specially crafted HTTP cookies, potentially leading to unintended memory disclosure. In production builds, the impact is expected to be limited to incorrect output rather than consistent crashes.
