Yahoo! Messenger URL Handler Denial of Service Vulnerability

CVE-2005-1618 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

The YMSGR URL handler in Yahoo! Messenger 5.x through 6.0 allows remote attackers to cause a denial of service (disconnect) via a room login or a room join request packet with a third : (colon) and an & (ampersand), which causes Messenger to send a corrupted packet to the server, which triggers a disconnect from the server.
