| Description: | Ruby is an extensible, interpreted, object-oriented, scripting language. Ithas features to process text files and to do system management tasks.It was found that Ruby did not reinitialize the PRNG (pseudorandom numbergenerator) after forking a child process. This could eventually lead to thePRNG returning the same result twice. An attacker keeping track of thevalues returned by one child process could use this flaw to predict thevalues the PRNG would return in other child processes (as long as theparent process persisted). (CVE-2011-3009)A flaw was found in the Ruby SecureRandom module. When using theSecureRandom.random_bytes class, the PRNG state was not modified afterforking a child process. This could eventually lead toSecureRandom.random_bytes returning the same string more than once. Anattacker keeping track of the strings returned by one child process coulduse this flaw to predict the strings SecureRandom.random_bytes would returnin other child processes (as long as the parent process persisted).(CVE-2011-2705)This update also fixes the following bugs:* The ruby package has been upgraded to upstream point release 1.8.7-p352,which provides a number of bug fixes over the previous version. (BZ#706332)* The MD5 message-digest algorithm is not a FIPS-approved algorithm.Consequently, when a Ruby script attempted to calculate an MD5 checksum inFIPS mode, the interpreter terminated unexpectedly. This bug has been fixedand an exception is now raised in the described scenario. (BZ#717709)* Due to inappropriately handled line continuations in the mkconfig.rbsource file, an attempt to build the ruby package resulted in unexpectedtermination. An upstream patch has been applied to address this issue andthe ruby package can now be built properly. (BZ#730287)* When the 32-bit ruby-libs library was installed on a 64-bit machine, themkmf library failed to load various modules necessary for buildingRuby-related packages. This bug has been fixed and mkmf now works properlyin the described scenario. (BZ#674787)* Previously, the load paths for scripts and binary modules were duplicatedon the i386 architecture. Consequently, an ActiveSupport test failed. Withthis update, the load paths are no longer stored in duplicates on the i386architecture. (BZ#722887)This update also adds the following enhancement:* With this update, SystemTap probes have been added to the ruby package.(BZ#673162)All users of ruby are advised to upgrade to these updated packages, whichresolve these issues and add this enhancement. |
