Debian DSA-4051-1 Curl Critical Update: Buffer Overrun & FTP Flaw

CVE-2017-8816

Alex Nichols discovered a buffer overrun flaw in the NTLM authentication
code which can be triggered on 32bit systems where an integer overflow
might occur when calculating the size of a memory allocation.

CVE-2017-8817

Fuzzing by the OSS-Fuzz project led to the discovery of a read out of
bounds flaw in the FTP wildcard function in libcurl. A malicious server
could redirect a libcurl-based client to an URL using a wildcard pattern,
triggering the out-of-bound read.

For the oldstable distribution (jessie), these problems have been fixed
in version 7.38.0-4+deb8u8.

For the stable distribution (stretch), these problems have been fixed in
version 7.52.1-5+deb9u3.
