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.
|
||
|
|
|
||
|
|
Subsequent refactoring of the netgroup cache only added more uses of
|
||
|
|
xmalloc and xrealloc. Uses of xmalloc and xrealloc in other parts of
|
||
|
|
nscd only occur during startup of the daemon and so are not affected by
|
||
|
|
client requests that could trigger an out of memory followed by
|
||
|
|
termination.
