14 January 2019

PEAR could be made to run programs if it processed a specially crafted file.



  • php-pear - PHP Extension and Application Repository


Fariskhi Vidyan discovered that PEAR Archive_Tar incorrectly handled
certain archive paths. A remote attacker could possibly use this issue to
execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10
Ubuntu 18.04
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
