(AV:N/AC:M/Au:N/C:P/I:P/A:P)

RedHat

finch (Unknown) pidgin (Unknown)

Целочисленное переполнение в функциях msn_slplink_process_msg в обработчике протокола MSN в libpurple/protocols/msn/slplink.c и libpurple/protocols/msnp9/slplink.c в Pidgin и Adium позволяет злоумышленникам, действующим удаленно, выполнить произвольный код, используя некорректное SLP-сообщение со специально сформированным значением смещения.

Для устранения уязвимости необходимо установить последнюю версию продукта, соответствующую используемой платформе. Необходимую информацию можно получить по адресу:
