Description

It was discovered that APT did not re-verify downloaded files when the If-Modified-Since wasn't met. (CVE-2014-0487)

It was discovered that APT did not invalidate repository data when it switched from an unauthenticated to an authenticated state. (CVE-2014-0488)

It was discovered that the APT Acquire::GzipIndexes option caused APT to skip checksum validation. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS, and was not enabled by default. (CVE-2014-0489)

It was discovered that APT did not correctly validate signatures when downloading source packages using the download command. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-0490).

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.
