Hello,

Two issues were found in unzip 6.0:

* A heap overflow triggered by unzipping a file with password (e.g
unzip -p -P x sigsegv.zip)
* A denegation of service with a file that never finishes unzipping
(e.g. unzip sigxcpu.zip).

Upstream is notified. Nevertheless the test cases as well as the
valgrind and the adress sanitizer reports of the heap overflow case
are attached (as a single file) in case someone wants to provide some
feedback. These issues were found with QuickFuzz.

Regards,
Gustavo.


Can CVEs be assigned?

Thanks in advance,
