Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id<br />
<br />
Use check_add_overflow() to guard against potential integer overflows<br />
when adding the binary blob lengths and the size of an asymmetric_key_id<br />
structure and return ERR_PTR(-EOVERFLOW) accordingly. This prevents a<br />
possible buffer overflow when copying data from potentially malicious<br />
X.509 certificate fields that can be arbitrarily large, such as ASN.1<br />
INTEGER serial numbers, issuer names, etc.
