Subject: Re: CVE Request - OpenSLP 2.0 Memory Corruption
-----BEGIN PGP SIGNED MESSAGE-----

> The following commit fixes a memory corruption bug that I reported in OpenSLP:

> https://sourceforge.net/p/openslp/mercurial/ci/34fb3aa5e6b4997fa21cb614e480de36da5dbc9a/
>
> Below are the details of the issue:
>
> static int SLPFoldWhiteSpace(size_t len, char * str)
> {
> char * p = str, * ep = str + len;
> while (p < ep)
> {
> if (isspace(*p))
> {
> char * ws2p = ++p;
> while (isspace(*p))
> p++;
> len -= p - ws2p;
> memmove(ws2p, p, ep - p);
>
> The outer while loop checks for p < ep, but lack of bound check in
> inner while loop could result in p > ep. This will result in passing a
> very large 'size_t len' (ep - p) parameter for memmove().
