perl vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - libcgi-fast-perl - libperl-dev - libperl5.8 - perl - perl-base - perl-debug - perl-doc - perl-modules - perl-suid Description : Two exploitable vulnerabilities involving setuid-enabled perl scripts have been discovered. The package "perl-suid" provides a wrapper around perl which permits to use setuid-root perl scripts, i.e. user-callable Perl scripts which have full root rights. Previous versions permited users to overwrite arbitrary files by setting the PERLIO_DEBUG environment variable and calling an arbitrary setuid-root perl script. The file that PERLIO_DEBUG points to was then overwritten by Perl debug messages. This did not permit precise control over the file content, but could destroy important data. PERLIO_DEBUG is now ignored for setuid scripts. (CVE-2005-0155) In addition, calling a setuid-root perl script with a very long path caused a buffer overflow if PERLIO_DEBUG was set. This buffer overflow could be exploited to execute arbitrary files with full root rights. (CVE-2005-0156) Solution : Upgrade to : - libcgi-fast-perl-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - libperl-dev-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - libperl5.8-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-base-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-debug-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-doc-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-modules-5.8.4-2ubuntu0.3 (Ubuntu 4.10) - perl-suid-5.8.4-2ubuntu0.3 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
