Debian Security Advisory DSA-3992-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso

Package : curl
CVE ID : CVE-2017-1000100 CVE-2017-1000101 CVE-2017-1000254
Debian Bug : 871554 871555 877671
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.
