Vulnerabilidades

AOL Instant Messenger (AIM) 4.7 allows remote attackers to cause a denial of service (application crash) via a long filename, possibly caused by a buffer overflow.

The Audio Setup Wizard (asw.dll) in Yahoo! Messenger 6.0.0.1750, and possibly other versions, allows attackers to arbitrary code by placing a malicious ping.exe program into the Messenger program directory, which is installed with weak default permissions.

Yahoo! Messenger 6.0.0.1750, and possibly other versions before 6.0.0.1921, does not properly display long filenames in file dialog boxes, which could allow remote attackers to trick users into downloading and executing programs via file names containing a large number of spaces and multiple file extensions.

Gadu-Gadu allows remote attackers to gain sensitive information and read files from the _cache directory of other users via a DCC connection and a CTCP packet that contains a 1 as the type and a 4 as the subtype.

Integer overflow in Gadu-Gadu allows remote attackers to cause a denial of service (disk consumption) via a user packet to the DCC file transfer capability with an invalid file length.

Stack-based buffer overflow in the code that sends images in Gadu-Gadu allows remote attackers to execute arbitrary code via a large image filename.

Directory traversal vulnerability in Gadu-Gadu allows remote attackers to read arbitrary files via .. (dot dot) sequences in a DCC connection with a CTCP packet that contains a 1 as the type and a 4 as the subtype.

Cross-site scripting vulnerability in the parser for Gadu-Gadu allows remote attackers to inject arbitrary web script or HTML via (1) http:// or (2) news:// URLs, a different vulnerability than CVE-2004-1410.

Cross-site scripting (XSS) vulnerability in Gadu-Gadu build 155 and earlier allows remote attackers to inject arbitrary web script via a URL, which is echoed in a popup window that displays a parsing error message, a different vulnerability than CVE-2004-1229.

The Buddy icon file for AOL Instant Messenger (AIM) 4.3 through 5.5 is created in a predictable location, which may allow remote attackers to use a shell: URI to exploit other vulnerabilities that involve predictable locations.

Gadu-Gadu allows remote attackers to bypass the "image send" option by sending a very small image file, which could be used in conjunction with image-related vulnerabilities.

Gadu-Gadu build 155 and earlier allows remote attackers to cause a denial of service (infinite loop) via a message that contains an image whose filename does not start with restricted characters.

Gadu-Gadu 6.1 build 156 allows remote attackers to cause a denial of service (application hang) via a message that contains many special strings that are converted to images.

Buffer overflow in Vypress Messenger 3.5.1 and earlier allows remote attackers to execute arbitrary code via a message with a long first field.

Buffer overflow in the goaway function in the aim:goaway URI handler for AOL Instant Messenger (AIM) 5.5, including 5.5.3595, allows remote attackers to execute arbitrary code via a long Away message.

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)…

The Base64 function in PopMessenger 1.60 (before 20 Sep 2004) and earlier allows remote attackers to cause a denial of service (application crash) via invalid characters in a message, which causes several alert dialogs to be displayed and leads to a crash.

Heap-based buffer overflow in the image sending feature in Gadu-Gadu 6.0 build 149 allows remote attackers to execute arbitrary code via a crafted GG_MSG_IMAGE_REPLY message.

Microsoft MSN Messenger 6.0 and 6.1 does not properly handle certain requests, which allows remote attackers to read arbitrary files.

Buffer overflow in Yahoo Instant Messenger 5.6.0.1351 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long filename in the download feature.

Buffer overflow in AOL Instant Messenger (AIM) 5.2.3292 allows remote attackers to execute arbitrary code via an aim:getfile URL with a long screen name.

Buffer overflow in Yahoo! Messenger 5.6 allows remote attackers to cause a denial of service (crash) via a file send request (sendfile) with a large number of "%" (percent) characters after the Yahoo ID.

Buffer overflow in the file & folder transfer mechanism for IP Messenger for Win 2.00 through 2.02 allows remote attackers to execute arbitrary code via file with a long filename, which triggers the overflow when the user saves the file.

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.
