Summary

Several security issues were fixed in IPython.

Software Description:

It was discovered that IPython incorrectly processed REST API POST requests.

An attacker could possibly use this issue to launch a cross-site request

forgery (CSRF) attack and leak user's sensitive information. This issue

only affected Ubuntu 14.04 ESM. (CVE-2015-5607)

It was discovered that IPython did not properly manage cross user temporary

files. A local attacker could possibly use this issue to execute arbitrary

code. This issue only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM.
