Vulnerability Note VU#582498
InnerMedia DynaZip library vulnerable to buffer overflow via long file names
Releases prior to version 5.00.04 of the InnerMedia DynaZip compression library contain a buffer overflow that may allow a remote attacker to execute arbitrary code.
DynaZip is a popular compression library for the Microsoft Windows platform. A bounds checking deficiency in DynaZip may allow a buffer overflow. An attacker can exploit this vulnerability by creating a zip archive containing files with long names. Depending on the version of DynaZip and the length of the file names, a buffer overflow can occur when a user accesses a specially crafted archive.
According to InnerMedia, DynaZip versions prior to and including 5.00.03 are vulnerable. DynaZip version 5.00.04 and later, as well as DynaZip Max Secure version 6.00.01 and later are not affected by this vulnerability.
If a remote attacker can persuade a user to access a specially crafted zip file, the attacker may be able to execute arbitrary code on that user's system, possibly with elevated privileges.
