Description

Eric Peterson and Lin Hua Cheng discovered that Django incorrectly handled session records. A remote attacker could use this issue to cause a denial of service. (CVE-2015-5143)

Sjoerd Job Postmus discovered that DJango incorrectly handled newline characters when performing validation. A remote attacker could use this issue to perform header injection attacks. (CVE-2015-5144).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
