A vulnerability in Microsoft Outlook Express’s NNTP response parsing may allow an attacker to execute arbitrary code.
Microsoft Outlook Express contains support for Network News Transfer Protocol (NNTP) data, which is defined in RFC 977 and RFC 2980. A flaw in Outlook Express’ handling of NNTP responses may lead to a buffer overflow condition if a specially-crafted reply is sent by a compromised or malicious NNTP server.
A remote, unauthenticated attacker with the ability to control an NNTP server that a host is connected to may be able to execute arbitrary code in the security context of the local user.
Apply an Update
Please see Microsoft Security Bulletin MS05-030 for more information, such as workarounds and patches.
Utilize Workarounds
A number of workarounds are indicated in Microsoft Security Bulletin MS05-030, including:
Block access to NNTP traffic, which commonly utilizes TCP port 119 and UDP port 119.
