A bug in the getgrouplist function can cause a buffer overflow if the size
|
||
|
|
of the group list is too small to hold all the user's groups. This overflow
|
||
|
|
can cause segmentation faults in user applications. This vulnerability
|
||
|
|
exists only when an administrator has placed a user in a number of groups
|
||
|
|
larger than that expected by an application.
