The following CRL triggers this behaviour:

Thanks,

[openssl-dev] [openssl.org #4531] openssl 1.0.2h: Parsing really large CRLs fails, side effect of change in x_name.c?

2016-05-04 Thread Jürgen Brauckmann via RT 
Hi.

Openssl 1.0.2h cannot parse really large CRLs anymore. "Really large" 
means > some 1MB.

It seems as if the new check in line 202 in x_name.c, commited 5 days 
ago, has a side effect beyond name decoding:

https://github.com/openssl/openssl/blob/OpenSSL_1_0_2-stable/crypto/asn1/x_name.c#L202

# openssl crl -in large_crl.pem
unable to load CRL

crl -out c -in cacrl.pem
unable to load CRL

All name structures in "large_crl.pem" have normale sizes, but it 
contains a large number of revoked certificates:

# openssl-102g crl -in large_crl.pem -noout -issuer
issuer=/C=DE/O=client-1/CN=Testinstanz client-1

# openssl-102g crl -in large_crl.pem -noout  | grep "Revocation Date:" | 
wc -l
49813

Best regards,
   Jürgen
