USN222-2 : perl vulnerability |
||
perl vulnerability 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 : USN-222-1 fixed a vulnerability in the Perl interpreter. It was discovered that the version of USN-222-1 was not sufficient to handle all possible cases of malformed input that could lead to arbitrary code execution, so another update is necessary. Original advisory: Jack Louis of Dyad Security discovered that Perl did not sufficiently check the explicit length argument in format strings. Specially crafted format strings with overly large length arguments led to a crash of the Perl interpreter or even to execution of arbitrary attacker-defined code with the rights of the user running the Perl program. However, this attack was only possible in insecure Perl programs which use variables with user-defined values in string interpolations without checking their validity. Solution : Upgrade to : - libcgi-fast-perl-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - libperl-dev-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - libperl5.8-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-base-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-debug-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-doc-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-modules-5.8.7-5ubuntu1.2 (Ubuntu 5.10) - perl-suid-5.8.7-5ubuntu1.2 (Ubuntu 5.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
