| Vetor | AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
libcacard versions prior to 2.5.3
Description
The issue is related to a memory leak in the
vcard apdu new function, located in the card 7816.c file of the libcacard library. This memory leak allows local guest OS users to cause a denial of service by consuming host memory. The denial of service is achieved through vectors related to allocating a new APDU object.Recommendations
For versions prior to 2.5.3, update to version 2.5.3 or later to resolve the issue. As a temporary workaround, consider restricting the allocation of new APDU objects to minimize the risk of exploitation.
