Title: cURL/libcurl: Buffer overflow in the handling of TFTP URLs (GLSA 200603-19)
Date: March 21, 2006
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 is a command line tool for transferring files with URL syntax, supporting numerous protocols. libcurl is the corresponding client-side library.
Vulnerable: < 7.15.3
Unaffected: >= 7.15.1-r1 < 7.15.2
Unaffected: >= 7.15.3
Unaffected: <= 7.14.1
Architectures: All supported architectures
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"
