Coverity static analysis, suspicious bitwise logical expression, DigestUtil (Elytron) ------------------------------------------------------------------------------------- Key: WFLY-8097 URL: https://issues.jboss.org/browse/WFLY-8097 Project: WildFly Issue Type: Bug Components: Security Reporter: Martin Choma Assignee: Ilia Vassilev Priority: Critical Coverity found suspicious logical operation https://scan7.coverity.com/reports.htm#v23632/p11778/fileInstanceId=95638... See detailed description of possible problem in [1] If I extend DigestUtilTest#testDecodeByteOrderedInteger with case from [1], test fails {code} byte[] inputFF = CodePointIterator.ofString("000000FF").hexDecode().drain(); assertEquals(0xFF, decodeByteOrderedInteger(inputFF, 0, 4)); {code} If I change decodeByteOrderedInteger implementation according to [1], all tests passes. {code} result |= (buf[offset + i] & 0xff); {code} [1] http://findbugs.sourceforge.net/bugDescriptions.html#BIT_IOR_OF_SIGNED_BYTE Setting to high priority, because correct behavior of SASL Digest mechanism could be impacted.
