CVE-2010-1513

TITLE

Ziproxy of src/image.c Integer overflow vulnerability

DESCRIPTION

Multiple integer overflows in src/image.c in Ziproxy before 3.0.1 allow remote attackers to execute arbitrary code via (1) a large JPG image, related to the jpg2bitmap function or (2) a large PNG image, related to the png2bitmap function, leading to heap-based buffer overflows. Ziproxy is a forwarded, non-cached, compressed HTTP proxy server. Ziproxy can compress images into low quality JPEG files or JPEG 2000 and compress (gzip or) HTML and other text-like data. Ziproxy has an integer overflow, and a remote attacker can exploit the vulnerability to execute arbitrary instructions with application privileges. Ziproxy is prone to multiple integer-overflow vulnerabilities because it fails to properly validate user-supplied data. Failed exploit attempts will likely result in denial-of-service conditions. Ziproxy 3.0 is vulnerable; other versions may also be affected. ====================================================================== Secunia Research 24/05/2010 - Ziproxy Two Integer Overflow Vulnerabilities - ====================================================================== Table of Contents Affected Software....................................................1 Severity.............................................................2 Vendor's Description of Software.....................................3 Description of Vulnerability.........................................4 Solution.............................................................5 Time Table...........................................................6 Credits..............................................................7 References...........................................................8 About Secunia........................................................9 Verification........................................................10 ====================================================================== 1) Affected Software * Ziproxy 3.0.0 NOTE: Other versions may also be affected. ====================================================================== 2) Severity Rating: Highly critical Impact: System access Where: Remote ====================================================================== 3) Vendor's Description of Software "Ziproxy is forwarding, non-caching, compressing HTTP proxy server.
