From the upstream advisory :
nvalid ASN1 module definition for CMS.
CMS structures containing OriginatorInfo are mishandled this can write to
invalid memory addresses or free up memory twice
This bug is only present in the CMS code: the older PKCS#7 code is not affected.
CMS is only present in OpenSSL 0.9.8h and later where it is disabled by
default and 1.0.0 where it is enabled by default.
Users of OpenSSL CMS code should update to 0.9.8o or 1.0.0a which contains a
patch to correct this issue.
Thanks to Ronald Moesbergen for reporting this issue.
This has been corrected upstream via:
Not vulnerable. These issues did not affect the versions of OpenSSL as shipped with Red Hat Enterprise Linux 3, 4, or 5.
