A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest...

This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake.

If the host na...
