Vulnerability Note VU#383779

ZIP archives containing files with large filenames can cause buffer overflows

Original Release date: 02 Oct 2002 | Last revised: 06 Jan 2003


Multiple file decompression utilities contain buffer overflow vulnerabilities for which the impacts vary.


Researchers at Rapid7, Inc. have discovered that multiple file decompression utilities are susceptible to buffer overflows as a result of large filenames embedded in crafted ZIP archive files. When affected users attempt to decompress these ZIP files, the buffer overflow may result in execution of arbitrary code.


The impact of this vulnerability may vary depending upon the product and its execution environment. Typically, successful exploitation of a buffer overflow will allow the attacker to execute arbitrary code with the privileges of the user running the application.
