curl vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in curl.
Software description
Daniel Stenberg discovered that curl incorrectly handled large floating
point output. A remote attacker could use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-9586)
Even Rouault discovered that curl incorrectly handled large file names when
doing TFTP transfers. A remote attacker could use this issue to cause curl
to crash, resulting in a denial of service, or possibly obtain sensitive
memory contents. (CVE-2017-1000100)
Brian Carpenter and Yongji Ouyang discovered that curl incorrectly handled
numerical range globbing. A remote attacker could use this issue to cause
curl to crash, resulting in a denial of service, or possibly obtain
sensitive memory contents. (CVE-2017-1000101)
Max Dymond discovered that curl incorrectly handled FTP PWD responses. A
remote attacker could use this issue to cause curl to crash, resulting in a
denial of service. (CVE-2017-1000254)
Brian Carpenter discovered that curl incorrectly handled the --write-out
command line option. A local attacker could possibly use this issue to
obtain sensitive memory contents. (CVE-2017-7407)
