GLSA-200603-19 : cURL/libcurl: Buffer overflow in the handling of TFTP URLs
High Nessus Plugin ID 21126
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200603-19 (cURL/libcurl: Buffer overflow in the handling of TFTP URLs)
Ulf Harnhammar reported a possible buffer overflow in the handling of TFTP URLs in libcurl due to the lack of boundary checks.
An attacker could exploit this vulnerability to compromise a user's system by enticing the user to request a malicious URL with cURL/libcurl or to use a HTTP server redirecting to a malicious TFTP URL.
There is no known workaround at this time.
SolutionAll cURL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/curl-7.15.1-r1'
