GLSA-201709-12 : Perl: Race condition vulnerability

medium Nessus Plugin ID 103280

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201709-12 (Perl: Race condition vulnerability)

 A race condition occurs within concurrent environments. This condition was discovered by The cPanel Security Team in the rmtree and remove_tree functions in the File-Path module before 2.13 for Perl. This is due to the time-of-check-to-time-of-use (TOCTOU) race condition between the stat() that decides the inode is a directory and the chmod() that tries to make it user-rwx.
 Impact :

 A local attacker could exploit this condition to set arbitrary mode values on arbitrary files and hence bypass security restrictions.
 Workaround :

 There is no known workaround at this time.

Solution

All Perl users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/perl-5.24.1-r2' All File-Path users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=perl-core/File-Path-2.130.0' All Perl-File-Path users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=virtual/perl-File-Path-2.130.0'
