+ <description>
+ <p>
+ 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.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ Applications that use getgrouplist can crash.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ It is recommended that all Gentoo Linux users update their systems as
+ follows:
+ </p>
+ <code>
+ # emerge sync
+ # emerge -pv '&gt;=sys-libs/glibc-2.2.5'
+ # emerge '&gt;=sys-libs/glibc-2.2.5'
+ # emerge clean</code>
