Debian DSA-800-1 : pcre3 - integer overflow

An integer overflow with subsequent buffer overflow has been detected in PCRE, the Perl Compatible Regular Expressions library, which allows an attacker to execute arbitrary code.

Since several packages link dynamically to this library you are advised to restart the corresponding services or programs respectively. The command ‘apt-cache showpkg libpcre3’ will list the corresponding packages in the ‘Reverse Depends:’ section.
