Description Jan Lieskovsky 2012-10-11 15:29:37 UTC
A security flaw was found in the way ibacm, an InfiniBand communication manager assistant, created files used by ib_acm service - they were created with world writable permissions. A local attacker could use this flaw to 1) overwrite content of ib_acm daemon log file or 2) overwrite content of ib_acm daemon ibacm.port file (ability to mask certain actions or cause ib_acm to run on non-default port).
