Severity: Normal Title: cURL: NTLM username stack overflow Date: October 22, 2005 Bugs: #109097 ID: 200510-19

Synopsis ========
cURL is vulnerable to a buffer overflow which could lead to the execution of arbitrary code.
Background ==========
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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/curl < 7.15.0 >= 7.15.0
Description ===========
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.
Resolution ==========
All cURL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.0"
