Doc Text:
A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and other applications for web communication. When processing cookies with specially crafted expiration dates, the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of memory contents, potentially exposing sensitive information from the process using libsoup.

Description OSIDB Bzimport 2025-09-26 07:19:27 UTC
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 soup_date_time_to_string() 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.
