Vulnerability Assessment Details

USN228-1 : curl vulnerability

Vulnerability Assessment Summary
curl vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- curl
- libcurl2
- libcurl2-dbg
- libcurl2-dev
- libcurl2-gssapi
- libcurl3
- libcurl3-dbg
- libcurl3-dev
- libcurl3-gssapi


Description :

Stefan Esser discovered several buffer overflows in the handling of
URLs. By attempting to load an URL with a specially crafted invalid
hostname, a local attacker could exploit this to execute arbitrary
code with the rights of the application that uses the cURL
library.

It is not possible to trick cURL into loading a malicious URL with an
HTTP redirect, so this vulnerability was usually not exploitable
remotely. However, it could be exploited locally to e. g. circumvent
PHP security restrictions.

Solution :

Upgrade to :
- curl-7.14.0-2ubuntu1.2 (Ubuntu 5.10)
- libcurl2-7.11.2-12ubuntu3.3 (Ubuntu 5.04)
- libcurl2-dbg-7.12.0.is.7.11.2-1ubuntu0.3 (Ubuntu 4.10)
- libcurl2-dev-7.11.2-12ubuntu3.3 (Ubuntu 5.04)
- libcurl2-gssapi-7.12.0.is.7.11.2-1ubuntu0.3 (Ubuntu 4.10)
- libcurl3-7.14.0-2ubuntu1.2 (Ubuntu 5.10)
- libcurl3-dbg-7.14.0-2ubuntu1.2 (Ubuntu 5.10)
- libcurl3-dev-7.14.0-2ubuntu1.2 (Ubuntu 5.10)
- libcurl3-gssapi-7.14.0-2ubuntu1.2 (Ubuntu 5.10)
