IBM DB2 PUBLIC security bypass
|ibm-db2-public-security-bypass (61872)||Medium Risk|
IBM DB2 could allow a remote attacker to bypass security restrictions. An error during the revocation of privileges on a database object from the PUBLIC group results in the dependent functions not being marked INVALID. An attacker could exploit this vulnerability to bypass security restrictions to execute privileges on the functions.
Apply IBM APAR IC68015, available from IBM Support and Downloads. See References.
