Severity: Normal Title: curl: NTLM response buffer overflow Date: March 16, 2005 Bugs: #82534 ID: 200503-20

Synopsis ========
curl is vulnerable to a buffer overflow which could lead to the execution of arbitrary code.
Background ==========
curl is a command line tool for transferring files via many different protocols.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/curl < 7.13.1 >= 7.13.1
Description ===========
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.
Resolution ==========
All curl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/curl-7.13.1"
