Routine

LOW 2.1WATCHLISTDOWNGRADEMITIGATE

CVE-2005-1410 is a low-severity flaw (CVSS 2.1) affecting postgresql, secure linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The tsearch2 module in PostgreSQL 7.4 through 8.0.x declares the (1) dex_init, (2) snb_en_init, (3) snb_ru_init, (4) spell_init, and (5) syn_init functions as "internal" even when they do not take an internal argument, which allows attackers to cause a denial of service (application crash) and possibly have other impacts via SQL commands that call other functions that accept internal arguments.

dnf --showduplicates list postgresql sudo dnf downgrade postgresql-<VERSION_BEFORE_7.4> sudo dnf versionlock add postgresql

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.
