Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

cURL security advisory :

When libcurl is given either

1. a file: URL that doesn't use two slashes following the colon, or

2. is told that file is the default scheme to use for URLs without

... and the given path starts with a drive letter and libcurl is built
for Windows or DOS, then libcurl would copy the path with a wrong
offset, so that the end of the given path would write beyond the
malloc buffer. Up to seven bytes too much.

We are not aware of any exploit of this flaw.
