Package: krb5-pkinit
Version: 1.15-1
Severity: normal
Dear Maintainer,
In file /krb5-1.15.1/src/plugins/preauth/pkinit/pkinit_crypto_openssl.h
I have found constant:
#define DN_BUF_LEN 256
So, the size of DN is limited by 256 bytes. It is very small and can be
easily overflowed, especially if DN contains utf8-encoded CN/O/OU.
In this case PKINIT failed with error 'stack smashing detected'.
Please, consider to increase DN_BUF_LEN or use dynamic memory allocation
for DN buffer.
