Debian DSA-3232-1 : curl - security update

High Nessus Plugin ID 83003

Synopsis

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

Description

Several vulnerabilities were discovered in cURL, an URL transfer library :

- CVE-2015-3143 NTLM-authenticated connections could be wrongly reused for requests without any credentials set, leading to HTTP requests being sent over the connection authenticated as a different user. This is similar to the issue fixed in DSA-2849-1.

- CVE-2015-3144 When parsing URLs with a zero-length hostname (such as 'http://:80'), libcurl would try to read from an invalid memory address. This could allow remote attackers to cause a denial of service (crash). This issue only affects the upcoming stable (jessie) and unstable (sid) distributions.

- CVE-2015-3145 When parsing HTTP cookies, if the parsed cookie's 'path' element consists of a single double-quote, libcurl would try to write to an invalid heap memory address. This could allow remote attackers to cause a denial of service (crash). This issue only affects the upcoming stable (jessie) and unstable (sid) distributions.

- CVE-2015-3148 When doing HTTP requests using the Negotiate authentication method along with NTLM, the connection used would not be marked as authenticated, making it possible to reuse it and send requests for one user over the connection authenticated as a different user.

Solution

Upgrade the curl packages.

For the stable distribution (wheezy), these problems have been fixed in version 7.26.0-1+wheezy13.

For the upcoming stable distribution (jessie), these problems have been fixed in version 7.38.0-4+deb8u1.
