Heap-based buffer overflow in Microsoft MSN Messenger 6.2, 7.0, and 7.5, and Live Messenger 8.0 allows user-assisted remote attackers to execute arbitrary code via unspecified vectors involving video conversation handling in Web Cam and video chat sessions.CVE-2007-3436microsoftmsn_messengerEPSS score12.66%
Microsoft MSN Messenger 4.7 on Windows XP allows remote attackers to cause a denial of service (resource consumption) via a flood of SIP INVITE requests to the port specified for voice conversation.CVE-2005-0562microsoftmsn_messengerEPSS score23.17%
GIF file validation error in MSN Messenger 6.2 allows remote attackers in a user's contact list to execute arbitrary code via a GIF image with an improper height and width.CVE-2004-0597greg_roelofslibpng+3EPSS score81.86%
Multiple buffer overflows in libpng 1.2.5 and earlier, as used in multiple products, allow remote attackers to execute arbitrary code via malformed PNG images in which (1) the png_handle_tRNS function does not properly validate the length of transparency chunk (tRNS) data, or the (2) png_handle_sBIT or (3) png_handle_hIST functions do not perform sufficient bounds checking.CVE-2004-0122microsoftmsn_messengerEPSS score22.47%
Microsoft MSN Messenger 6.0 and 6.1 does not properly handle certain requests, which allows remote attackers to read arbitrary files.CVE-2002-1698microsoftmsn_messengerEPSS score15.51%
Buffer overflow in Microsoft MSN Messenger Service 1.0 through 4.6 allows remote attackers to cause a denial of service (crash) via a long FN (font) argument in the message header.CVE-2002-1831microsoftmsn_messengerEPSS score22.26%
Microsoft MSN Messenger Service 1.0 through 4.6 allows remote attackers to cause a denial of service (crash) via an invite request that contains hex-encoded spaces (%20) in the Invitation-Cookie field.CVE-2002-0472microsoftmsn_messengerEPSS score11.88%
MSN Messenger Service 3.6, and possibly other versions, uses weak authentication when exchanging messages between clients, which allows remote attackers to spoof messages from other users.CVE-2002-0155microsoftmsn_messenger+1EPSS score24.10%
Buffer overflow in Microsoft MSN Chat ActiveX Control, as used in MSN Messenger 4.5 and 4.6, and Exchange Instant Messenger 4.5 and 4.6, allows remote attackers to execute arbitrary code via a long ResDLL parameter in the MSNChat OCX.CVE-2002-0228microsoftmsn_messengerEPSS score19.87%
Microsoft MSN Messenger allows remote attackers to use Javascript that references an ActiveX object to obtain sensitive information such as display names and web site navigation, and possibly more when the user is connected to certain Microsoft sites (or DNS-spoofed sites).CVE-2006-0363microsoftmsn_messengerEPSS score2.64%
The "Remember my Password" feature in MSN Messenger 7.5 stores passwords in an encrypted format under the HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\Creds registry key, which might allow local users to obtain the original passwords via a program that calls CryptUnprotectData, as demonstrated by the "MSN Password Recovery.exe" program. NOTE: it could be argued that local-only password recovery is inherently insecure because the decryption methods and keys must be stored somewhere on the local system, and are thus inherently accessible with varying degrees of effort. Perhaps this issue should not be included in CVE.
