PCRE: Buffer overflow

PCRE: Buffer overflow A buffer overflow vulnerability has been discovered in PCRE, allowing for the execution of arbitrary code and Denial of Service. libpcre glib 2008-03-17 2008-03-17 209067 209293 remote 7.6-r1 7.6-r1 2.14.6 2.14.0 2.14.6

PCRE is a Perl-compatible regular expression library. GLib includes a copy of PCRE.

PCRE contains a buffer overflow vulnerability when processing a character class containing a very large number of characters with codepoints greater than 255.

A remote attacker could exploit this vulnerability by sending a specially crafted regular expression to an application making use of the PCRE library, which could possibly lead to the execution of arbitrary code or a Denial of Service.

There is no known workaround at this time.

All PCRE users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.6-r1"

All GLib users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.14.6"
