- Summary
- [none]
- Details
-
In nbd-server in nbd before 3.24, there is an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name, resulting in a write to a dangling pointer. This issue exists for the NBDOPTINFO, NBDOPTGO, and NBDOPTEXPORT_NAME messages.
