Debian Security Advisory DSA-3992-1 [email protected]

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.
