SA Document Body
Multiple Security Vulnerabilities in ICU 3.2 Library Regular Expression Process
ing May Cause a Denial of Service (DoS)
1. Impact
Multiple security vulnerabilities in processing regular expressions in
the ICU 3.2 library shipped with Solaris may impact applications which
make use of this library. Depending on the application, this may allow
a local or remote unprivileged user to execute arbitrary code with the
privileges of the user running the application via a carefully crafted
regular expression which is processed by the application. This may
also result in a Denial of Service (DoS) to the application.
