medium Nessus Plugin ID 100828

Language:

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 scheme

... 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.

Solution

Update the affected package.
