29 May 2023
Perl could be made to install modules from untrusted sources.
Releases
Packages
- perl - Practical Extraction and Report Language
Details
It was discovered that Perl was not properly verifying TLS certificates
when using CPAN together with HTTP::Tiny to download modules over HTTPS.
If a remote attacker were able to intercept communications, this flaw
could potentially be used to install altered modules.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04
Ubuntu 16.04
-
perl
-
5.22.1-9ubuntu0.9+esm2
Available with Ubuntu Pro
Ubuntu 14.04
-
perl
-
5.18.2-2ubuntu1.7+esm5
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
