GLSA-200510-19 : cURL: NTLM username stack overflow
High Nessus Plugin ID 20081
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
SolutionAll cURL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/curl-7.15.0'
