CVE-2006-7228: Buffer Overflow
First published: Wed Nov 07 2007(Updated: )
<a href="https://access.redhat.com/security/cve/CVE-2006-7224">CVE-2006-7224</a> initially described several integer overflows in pcre, all described here: <a href="http://scary.beasts.org/security/CESA-2007-006.html">http://scary.beasts.org/security/CESA-2007-006.html</a> This id should be used to describe issue #2 in that advisory: 3) More possible integer overflow trouble. pcre_compile: --- if (min == 0) { length++; if (max > 0) length += (max - 1) * (duplength + 3 + 2*LINK_SIZE); } ... else { length += (min - 1) * duplength; if (max > min) /* Need this test as max=-1 means no limit */ length += (max - min) * (duplength + 3 + 2*LINK_SIZE) - (2 + 2*LINK_SIZE); } --- In both these cases, I see no reason why a malicious regexp pattern couldn't cause an integer overflow by using large min / max / duplength values. This will really mess up the critical "length" value.
