Package : libicu
Vulnerability : various
Problem type : local
Debian-specific: no
CVE Id(s) : 2007-4770 2007-4771
Debian Bug : 463688
Several local vulnerabilities have been discovered in libicu,
International Components for Unicode, The Common Vulnerabilities and
Exposures project identifies the following problems:
CVE-2007-4770
libicu in International Components for Unicode (ICU) 3.8.1 and earlier
attempts to process backreferences to the nonexistent capture group
zero (aka \0), which might allow context-dependent attackers to read
from, or write to, out-of-bounds memory locations, related to
corruption of REStackFrames.
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.
