    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.
