Impact: Accessing a maliciously crafted FTP server could result in
an unexpected application termination, information disclosure, or
arbitrary code execution
Description: Multiple vulnerabilities exist in WebKit's handling of
FTP directory listings. Accessing a maliciously crafted FTP server
may lead to information disclosure, unexpected application
termination, or execution of arbitrary code. This update addresses
the issues through improved parsing of FTP directory listings. These
issues do not affect Safari on Mac OS X systems. Credit to Michal
Zalewski of Google Inc. for reporting these issues.
