NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-rhnlib package and not the python2-rhnlib package as distributed by SLES.

It was found that Spacewalk, all versions through 2.9, did not safely compute client token checksums. An attacker with a valid, but expired, authenticated set of headers could move some digits around, artificially extending the session validity without modifying the checksum.
