potential integer overflow
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People

g_uzip_zlib patch
The implementation of z_alloc() in g_uzip_zlib.c uses malloc() to allocate
resources without any check for the size.
This may lead to integer overflow.
It is better to use mallocarray() here to prevent such risk.
