cURL: NTLM username stack overflow

cURL: NTLM username stack overflow cURL is vulnerable to a buffer overflow which could lead to the execution of arbitrary code. cURL 2005-10-22 2005-10-22 109097 remote 7.15.0 7.15.0

cURL is a command line tool and library for transferring files via many different protocols. It supports NTLM authentication to retrieve files from Windows-based systems.

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

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.

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.

All cURL users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.0"
