CVE-2005-4667: Info-zip unzip memory buffer overflow vulnerability

IInfo Zip · Unzip

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long arguments when it is invoked from other programs.
