GLSA-200510-19 : cURL: NTLM username stack overflow

High Nessus Plugin ID 20081

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-200510-19 (cURL: NTLM username stack overflow)

iDEFENSE reported that insufficient bounds checking on a memcpy() of the supplied NTLM username can result in a stack overflow.
Impact :

A remote attacker could setup a malicious server and entice an user to connect to it using a cURL client, potentially 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 when using cURL (the command line version). Workarounds for programs that use the cURL library depend on the configuration options presented by those programs.

Solution

All cURL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/curl-7.15.0'
