hi, New fixes or improved fixes, even for known flaw, get new CVE #. I was not sure about that a couple of months ago, but that's the answer I got when I asked about the policy for such cases. I think it makes even more sense in this particular flaw. Cheers, On Tue, Nov 16, 2010 at 7:30 AM, Huzaifa Sidhpurwala <huzaifas () redhat com> wrote:
Hi, This is regarding the "utf-8 security issue in php", which was discussed on this list[1] From the php bug[2], it is clear that this issue has been assigned CVE-2010-3870 However yesterday another CVE was assigned to this bug i.e. CVE-2009-5016[3] The upstream bug report, describes two issues: a. An integer overflow b. flaw in handling ill-formed UTF8 characters. The integer overflow issue was solved somewhere in year 2009, which was however not a complete fix since the ill-formed UTF8 chars., were still not properly validated. The rest of the issues were solved sometime back. It seems that the integer overflow is not exploitable on its own, you need to couple it with the second issue for the exploit to really work. Therefore do we really need two CVEs for this issue?
