<title>libpcre: Heap integer overflow</title>
libpcre is vulnerable to a heap integer overflow, possibly leading to the
execution of arbitrary code.
<product type="ebuild">libpcre</product>
<announced>August 25, 2005</announced>
<revised>August 25, 2005: 01</revised>
<package name="dev-libs/libpcre" auto="yes" arch="*">
<unaffected range="ge">6.3</unaffected>
<vulnerable range="lt">6.3</vulnerable>
libpcre is a library providing functions for Perl-compatible
regular expressions.
libpcre fails to check certain quantifier values in regular
expressions for sane values.
<impact type="high">
An attacker could possibly exploit this vulnerability to execute
arbitrary code by sending specially crafted regular expressions to
applications making use of the libpcre library.
There is no known workaround at this time.
All libpcre users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libpcre-6.3&quot;</code>
