nscd: Stack-based buffer overflow in netgroup cache
If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted
by client requests then a subsequent client request for netgroup data
may result in a stack-based buffer overflow. This flaw was introduced
in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.

nscd: Null pointer crashes after notfound response
If the Name Service Cache Daemon's (nscd) cache fails to add a not-found
netgroup response to the cache, the client request can result in a null
pointer dereference. This flaw was introduced in glibc 2.15 when the
cache was added to nscd.
This vulnerability is only present in the nscd binary.

nscd: netgroup cache may terminate daemon on memory allocation failure
The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or
xrealloc and these functions may terminate the process due to a memory
allocation failure resulting in a denial of service to the clients. The
flaw was introduced in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.

nscd: netgroup cache assumes NSS callback uses in-buffer strings
The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory
when the NSS callback does not store all strings in the provided buffer.
The flaw was introduced in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.

The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable.

GRUB2 does not call the module fini functions on exit, leading to Debian/Ubuntu's peimage GRUB2 module leaving UEFI system table hooks after exit. This lead to a use-after-free condition, and could possibly lead to secure boot bypass.
