|Gentoo Linux Security Advisory
Title: cURL: NTLM username stack overflow (GLSA 200510-19)
Date: October 22, 2005
cURL is vulnerable to a buffer overflow which could lead to the execution of arbitrary code.
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.
Vulnerable: < 7.15.0
Unaffected: >= 7.15.0
Architectures: All supported architectures
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"
iDefense Security Advisory 10.13.05
