ID CVE-2006-0898
Summary Crypt::CBC Perl module 2.16 and earlier, when running in RandomIV mode, uses an initialization vector (IV) of 8 bytes, which results in weaker encryption when used with a cipher that requires a larger block size than 8 bytes, such as Rijndael.

    description Red Hat Network Satellite Server version 5.1.1 is now available. This update includes fixes for a number of security issues in Red Hat Network Satellite Server components. This update has been rated as having low security impact by the Red Hat Security Response Team. During an internal security audit, it was discovered that Red Hat Network Satellite Server shipped with an XML-RPC script, manzier.pxt, which had a single hard-coded authentication key. A remote attacker who is able to connect to the Satellite Server XML-RPC service could use this flaw to obtain limited information about Satellite Server users, such as login names, associated email addresses, internal user IDs, and partial information about entitlements. (CVE-2008-2369) This release also corrects several security vulnerabilities in various components shipped as part of Red Hat Network Satellite Server 5.1. In a typical operating environment, these components are not exposed to users of Satellite Server in a vulnerable manner. These security updates will reduce risk in unique Satellite Server environments. A denial-of-service flaw was fixed in mod_perl. (CVE-2007-1349) Multiple cross-site scripting flaws were fixed in the image map feature in the JFreeChart package. (CVE-2007-6306) A flaw which could result in weak encryption was fixed in the perl-Crypt-CBC package. (CVE-2006-0898) Multiple flaws were fixed in the Apache Tomcat package. (CVE-2005-4838, CVE-2006-0254, CVE-2007-1355, CVE-2007-1358, CVE-2007-2449, CVE-2007-5461, CVE-2008-0128) Users of Red Hat Network Satellite Server 5.1 are advised to upgrade to 5.1.1, which resolves these issues.

    description The remote host is affected by the vulnerability described in GLSA-200603-15 (Crypt::CBC: Insecure initialization vector) Lincoln Stein discovered that Crypt::CBC fails to handle 16 bytes long initializiation vectors correctly when running in the RandomIV mode, resulting in a weaker encryption because the second part of every block will always be encrypted with zeros if the blocksize of the cipher is greater than 8 bytes. Impact : An attacker could exploit weak ciphertext produced by Crypt::CBC to bypass certain security restrictions or to gain access to sensitive data. Workaround : There is no known workaround at this time.
