GLSA-200503-20 : curl: NTLM response buffer overflow

medium Nessus Plugin ID 17345

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200503-20 (curl: NTLM response buffer overflow)

 curl fails to properly check boundaries when handling NTLM authentication.
 Impact :

 With a malicious server an attacker could send a carefully crafted NTLM response to a connecting client leading to the execution of arbitrary code with the permissions of the user running curl.
 Workaround :

 Disable NTLM authentication by not using the --anyauth or --ntlm options.

Solution

All curl users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/curl-7.13.1'
