HIGH 7.5DOWNGRADE

CVE-2014-1927 is a high-severity flaw (CVSS 7.5) affecting python-gnupg. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The shell_quote function in python-gnupg 0.3.5 does not properly quote strings, which allows context-dependent attackers to execute arbitrary code via shell metacharacters in unspecified vectors, as demonstrated using "$(" command-substitution sequences, a different vulnerability than CVE-2014-1928. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7323.

python-gnupg project python-gnupg DOWNGRADE

Affected: 0.3.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.3.5

1. Check installed version

apt-cache policy python-gnupg || rpm -q python-gnupg || python-gnupg --version

2. No fixed release: DOWNGRADE to a release before 0.3.5 (Debian / Ubuntu)

apt-cache madison python-gnupg sudo apt install python-gnupg=<VERSION_BEFORE_0.3.5> sudo apt-mark hold python-gnupg

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list python-gnupg sudo dnf downgrade python-gnupg-<VERSION_BEFORE_0.3.5> sudo dnf versionlock add python-gnupg

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
