CVE-2008-5005
HighSummary
Wielokrotne przepełnienia bufora na stosie w narzędziu IMAP Uniwersytetu Waszyngtońskiego oraz w programie Alpine i Panda IMAP umożliwiają lokalnym użytkownikom uzyskanie uprawnień oraz zdalnym atakującym wykonanie dowolnego kodu. Problem występuje w wyniku podania długiego argumentu rozszerzenia folderu w wierszu poleceń lub wysłania odpowiednio skonstruowanej wiadomości e-mail.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do systemów oraz możliwość wykonania złośliwego kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa. W szczególności, atakujący mogą uzyskać kontrolę nad systemem lub danymi użytkowników.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które eliminują te podatności. Dodatkowo, warto ograniczyć dostęp do programów tmail i dmail oraz monitorować ruch e-mailowy w celu wykrywania potencjalnych ataków.

Multiple stack-based buffer overflows in (1) University of Washington IMAP Toolkit 2002 through 2007c, (2) University of Washington Alpine 2.00 and earlier, and (3) Panda IMAP allow (a) local users to gain privileges by specifying a long folder extension argument on the command line to the tmail or dmail program; and (b) remote attackers to execute arbitrary code by sending e-mail to a destination mailbox name composed of a username and '+' character followed by a long string, processed by the tmail or possibly dmail program.
