Title: International Components for Unicode: Multiple vulnerabilities (GLSA 200803-20)
Date: March 11, 2008
Updated: May 28, 2009
Two vulnerabilities have been discovered in the International Components for Unicode, possibly resulting in the remote execution of arbitrary code or a Denial of Service.
International Components for Unicode is a set of C/C++ and Java libraries providing Unicode and Globalization support for software applications.
Vulnerable: < 3.8.1-r1
Unaffected: >= 3.8.1-r1
Unaffected: >= 3.6-r2 < 3.7
Architectures: All supported architectures
Will Drewry (Google Security) reported a vulnerability in the regular expression engine when using back references to capture characters (CVE-2007-4770). He also found that the backtracking stack size is not limited, possibly allowing for a heap-based buffer overflow (CVE-2007-4771).
A remote attacker could submit specially crafted regular expressions to an application using the library, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application or a Denial of Service.
There is no known workaround at this time.
All International Components for Unicode users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/icu-3.8.1-r1"
