Debian DSA-3992-1 : curl - security update

Description

Several vulnerabilities have been discovered in cURL, an URL transfer library. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2017-1000100 Even Rouault reported that cURL does not properly handle long file names when doing an TFTP upload. A malicious HTTP(S) server can take advantage of this flaw by redirecting a client using the cURL library to a crafted TFTP URL and trick it to send private memory contents to a remote server over UDP. - CVE-2017-1000101 Brian Carpenter and Yongji Ouyang reported that cURL contains a flaw in the globbing function that parses the numerical range, leading to an out-of-bounds read when parsing a specially crafted URL. - CVE-2017-1000254 Max Dymond reported that cURL contains an out-of-bounds read flaw in the FTP PWD response parser. A malicious server can take advantage of this flaw to effectively prevent a client using the cURL library to work with it, causing a denial of service.
