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. For the oldstable distribution (jessie), these problems have been fixed in version 7.38.0-4+deb8u6. For the stable distribution (stretch), these problems have been fixed in version 7.52.1-5+deb9u1. We recommend that you upgrade your curl packages.
