[jira] [Updated] (MINIFICPP-1379) Fix UUID parsing

     [ https://issues.apache.org/jira/browse/MINIFICPP-1379?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adam Debreceni updated MINIFICPP-1379:
--------------------------------------
    Description: 
The sscanf-based uuid parsing allows uuids in otherwise invalid formats:

// longer than the format (dropping the extra)

00000000-0000-0000-0000-123456789abcfffff

// containing non-hex characters as the last character (discarding 'Z' and yielding 11 as the last byte)

00000000-0000-0000-0000-123456789abZ

// extra hyphens in the middle of uuid (parsed as negative then converted to unsigned)

00000000-00-c0-0000-0000-123456789abc
