Wed Jun 10 16:12:47 2026: Request 9218 was acted upon. Transaction: Ticket created by [email protected] Queue: krb5 Subject: git commit Owner: [email protected] Requestors: Status: new Ticket <URL: https://krbdev.mit.edu/rt/Ticket/Display.html?id=9218 > Better validate key_data_ver in iprop decoding In ulog_conv_2dbentry(), when decoding an update's AT_KEYDATA attribute, the decoded key_data_ver value is used as a bound on the enctype and contents fields. Verify that this value does not exceed the sizes of the update's enctype and contents XDR arrays, to prevent reading past the end of those arrays. Also check against the expected lower bound.
