Gentoo Linux Security Advisory

Title: cURL: Arbitrary file access (GLSA 200903-21)
Severity: normal
Exploitable: remote
Date: March 09, 2009
Bug(s): #260361
ID: 200903-21

Synopsis

A vulnerability in cURL may allow for arbitrary file access.

Background

cURL is a command line tool for transferring files with URL syntax, supporting numerous protocols.

Affected Packages

Package: net-misc/curl
Vulnerable: < 7.19.4
Unaffected: >= 7.19.4
Architectures: All supported architectures


Description

David Kierznowski reported that the redirect implementation accepts arbitrary Location values when CURLOPT_FOLLOWLOCATION is enabled.

Impact

A remote attacker could possibly exploit this vulnerability to make remote HTTP servers trigger arbitrary requests to intranet servers and read or overwrite arbitrary files via a redirect to a file: URL, or, if the libssh2 USE flag is enabled, execute arbitrary commands via a redirect to an scp: URL.

Workaround

There is no known workaround at this time.

Resolution

All cURL users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.19.4"
