Описание
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.
Отчет
The Red Hat Product Security team has rated this vulnerability as High, since it can be triggered remotely without authentication or user interaction. While AddressSanitizer builds demonstrated crashes, the practical production impact is more likely limited to memory disclosure through malformed cookie headers. The root cause is insufficient bounds checking in cookie date formatting logic.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don’t meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to a widespread installation base, or stability. It is strongly recommended to apply vendor-supplied patches once available.
