Name of the Vulnerable Software and Affected Versions
CUPS versions 1.3.7 through 1.3.10
Description
The issue is related to a use-after-free vulnerability in the abstract file-descriptor handling interface in the
cupsdDoSelect function. This vulnerability allows remote attackers to cause a denial of service, resulting in a daemon crash or hang, by disconnecting during the listing of a large number of print jobs. The problem is caused by improperly maintaining a reference count.Recommendations
For versions 1.3.7 and 1.3.10, consider disabling the
cupsdDoSelect function as a temporary workaround until a patch is available. Restrict access to the scheduler in cupsd to minimize the risk of exploitation. Avoid using the affected interface during the listing of print jobs until the issue is resolved.Correção
