cURL/libcurl: Buffer overflow in the handling of TFTP URLs

cURL/libcurl: Buffer overflow in the handling of TFTP URLs libcurl is affected by a buffer overflow in the handling of URLs for the TFTP protocol, which could be exploited to compromise a user's system. curl March 21, 2006 March 21, 2006: 01 125766 remote 7.15.1-r1 7.15.3 7.14.1 7.15.3

cURL is a command line tool for transferring files with URL syntax, supporting numerous protocols. libcurl is the corresponding client-side library.

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.

All cURL users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.1-r1"
