ccm_process fails to process input buffer longer than 256 bytes #323
Description
Prerequisites
- Checked the developer manual
- Checked that your issue isn't already filed: https://github.com/issues?utf8=✓&q=repo%3Alibtom%2Flibtomcrypt
- Checked that your issue isn't related to TomsFastMath's limitation that PK operations can by default only be done with max. 2048bit keys
Description
If you call ccm_process with ptlen > 256 it loops for ever at this line https://github.com/libtom/libtomcrypt/blob/develop/src/encauth/ccm/ccm_process.c#L49 because y is just unsigned char and should be unsigned long
PR later
