[原文]IBM AIX 4.3.3 and AIX 5 allows remote attackers to cause a denial of service (CPU consumption or crash) via a flood of malformed TCP packets without any flags set, which prevents AIX from releasing the associated memory buffers.

- 受影响的程序版本

IBM AIX 4.3.3

- 漏洞讨论

AIX is a variant of the Unix Operating System distributed and maintained by IBM.

It has been reported that AIX does not properly handle malformed TCP packets. When an AIX system receives a TCP packet without flags set, it allocates a memory buffer to the packet and stores it in memory for an arbitrary length of time. By sending a large amount of this type of data, an attacker could crash a vulnerable AIX system.
