|Gentoo Linux Security Advisory
Title: libpcre: Heap integer overflow (GLSA 200508-17)
Date: August 25, 2005
libpcre is vulnerable to a heap integer overflow, possibly leading to the
execution of arbitrary code.
libpcre is a library providing functions for Perl-compatible
Vulnerable: < 6.3
Unaffected: >= 6.3
Architectures: All supported architectures
libpcre fails to check certain quantifier values in regular
expressions for sane values.
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 ">=dev-libs/libpcre-6.3"
