GLSA-200502-13 : Perl: Vulnerabilities in perl-suid wrapper

Medium Nessus Plugin ID 16450


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


The remote host is affected by the vulnerability described in GLSA-200502-13 (Perl: Vulnerabilities in perl-suid wrapper)

perl-suid scripts honor the PERLIO_DEBUG environment variable and write to that file with elevated privileges (CAN-2005-0155).
Furthermore, calling a perl-suid script with a very long path while PERLIO_DEBUG is set could trigger a buffer overflow (CAN-2005-0156).
Impact :

A local attacker could set the PERLIO_DEBUG environment variable and call existing perl-suid scripts, resulting in file overwriting and potentially the execution of arbitrary code with root privileges.
Workaround :

You are not vulnerable if you do not have the perlsuid USE flag set or do not use perl-suid scripts.


All Perl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-lang/perl
