Debian: DSA-1511-1 Critical: Libicu Local Buffer Overflow Threat

CVE-2007-4771
Heap-based buffer overflow in the doInterval function in regexcmp.cpp
in libicu in International Components for Unicode (ICU) 3.8.1 and
earlier allows context-dependent attackers to cause a denial of
service (memory consumption) and possibly have unspecified other
impact via a regular expression that writes a large amount of data to
the backtracking stack.

For the stable distribution (etch), these problems have been fixed in
version 3.6-2etch1.

For the unstable distribution (sid), these problems have been fixed in
version 3.8-6.

We recommend that you upgrade your libicu package.
