[原文]Buffer overflow in the progressive reader for libpng 1.2.x before 1.2.4, and 1.0.x before 1.0.14, allows attackers to cause a denial of service (crash) via a PNG data stream that has more IDAT data than indicated by the IHDR chunk.


[CNNVD]多种Web浏览器畸形PNG图象远程内存破坏漏洞(CNNVD-200208-117)

        
        Opera和Konqueror是两款WEB浏览程序。
        Opera和Konqueror在查看一些畸形PNG图象时存在漏洞,远程攻击者可以使浏览器产生内存破坏错误。
        远程攻击者可以构建包含畸形PNG图象的WEB页面,当Opera和Konqueror浏览器查看此文件时会导致浏览器进程发生段错误而崩溃。
        目前尚不知道是否可以利用执行任意指令。

libpng Progressive Reader Malformed PNG Overflow
Context Dependent Input Manipulation
Loss of Integrity Upgrade
Exploit Unknown Vendor Verified

- 漏洞描述

libpng contains an overflow condition in the progressive reader function. The issue is due to the progressive reader function not sanitizing user-supplied input. With a specially crafted PNG data stream containing malformed IDAT data, a context-dependent attacker can cause a buffer overflow to cause a denial of service or potentially execute arbitrary code.

- 漏洞讨论

libpng is reported to be prone to a security-related issue with regards to handling of overly wide images. It may be possible to corrupt memory with an overly wide PNG image. An attacker may be able to exploit this condition to execute arbitrary code with the privileges of an application or client which handles the overly wide image, though this possibility has not been confirmed.
