USN-726-1: curl vulnerability

Releases

• Ubuntu 8.10
• Ubuntu 8.04
• Ubuntu 7.10
• Ubuntu 6.06

Packages

• curl -

Details

It was discovered that curl did not enforce any restrictions when following
URL redirects. If a user or automated system were tricked into opening a URL to
an untrusted server, an attacker could use redirects to gain access to abitrary
files. This update changes curl behavior to prevent following "file" URLs after
a redirect.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.10

• libcurl3-gnutls - 7.18.2-1ubuntu4.1
• libcurl3 - 7.18.2-1ubuntu4.1

Ubuntu 8.04

• libcurl3-gnutls - 7.18.0-1ubuntu2.1
• libcurl3 - 7.18.0-1ubuntu2.1

Ubuntu 7.10

• libcurl3-gnutls - 7.16.4-2ubuntu1.1
• libcurl3 - 7.16.4-2ubuntu1.1

Ubuntu 6.06

• libcurl3-gnutls - 7.15.1-1ubuntu3.1
• libcurl3 - 7.15.1-1ubuntu3.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
