similar to: openssh portable and libressl portable cause recursion between arc4random and RAND_bytes

Hello, I have been doing some looking at openssl 0.9.7 and openssh3.5p1 and found a minor descrepancy. RAND_bytes() is called around line 69 of openbsd-compat/bsd-arc4random.c. It checks to see if the return is not zero. The RAND_bytes function can also return -1, too. All the code in openssl uses <=0 for the test rather than !. Best Regards, Steve Grubb

This morning dovecot died with the following messages in the errorlog. Any solution to this problem? I am using Fedora Core 1 on a SMP i686 box. imap-login: Mar 30 08:08:00 Fatal: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded dovecot: Mar 30 08:08:00 Error: Login process died too

Hi, with current test releases SSL doesn't work anymore for me on AIX 4.3 with dovecot-0.99.10-test14. It worked with 0.99.9.1. dovecot: Jun 23 19:42:23 Info: Dovecot starting up imap-login: Jun 23 19:42:25 Fatal: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded imap-login: Jun 23 19:42:25 Fatal: RAND_bytes() failed: error:24064064:random number

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at:

Hi, dovecot tries to use OpenSSL's PRNG to generate random numbers if there is no /dev/urandom found. Unfortunately, it is flawed in its present form, since the PRNG is not seeded before RAND_bytes() is called in src/lib/randgen.c (on systems which have /dev/urandom, OpenSSL automatically seeds its PRNG from the urandom device). Here's a patch to address this issue: it tries to seed

Now that ssh-rand-helper has been segregated into a separate program, I'd like to revisit an old question about its entropy gathering. - would it be desirable to make it possible for ssh-rand-helper to fall back to external commands if PRNGD cannot be reached, instead of choosing one or the other at compile time? - When using PRNGD, the program gets 48 bytes of entropy from PRNGD,

I woke up this morning and my dovecot server had died with the following in the dovecot.log file: pop3-login: Jan 23 10:23:08 Fatal: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded dovecot: Jan 23 10:23:08 Error: Login process died too early - shutting down dovecot: Jan 23 10:23:08 Error: child 16321 (login) returned error 89 How can I find out

Dovecot died twice today. This was in the maillog: Apr 9 17:50:27 ciscy pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded Apr 9 17:50:27 ciscy dovecot: Login process died too early - shutting down I think I can cause it to happen reliably and I'm asking for other to test this scenario: Open several terminal windows. In each, type

Hi. SunOS 4 is one system that relies on the strerror() in bsd-misc.[ch]. However, that replacement function does not have the right prototype. This is fixed in the patch below. There was also an error with sys_errlist not being explicitely declared. Also fixed. There was another weird link-time problem with bsd-misc.o being at the same time used by some *.o in libssh.a and using itself

Hi, Dovecot (pre-compiled version of Fedora Core 1, configured for Maildir) is running fine for me since a few days. It happened now twice to me that dovecot died with the following error message in /var/log/maillog: Feb 4 11:18:27 hundehuette imap-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded Feb 4 11:18:27 hundehuette dovecot: Login

http://dovecot.org/rc/ Just a few more changes: - --with-moduledir option to configure - compile fix to Solaris 10 - mbox syncing complains if mbox is modified while we have it locked and something goes wrong (lock settings are wrong) - maildir: RENAME xx inbox.xx makes sure INBOX is uppercased. - "RAND_bytes() failed:" SSL "fix" for fedora/redhat -------------- next

I'm using OpenSSH 2.3.0p1. When my users use ssh for the first time, using rhosts authentication, entropy.c drops the privs in prng_write_seedfile() at the setuid(original_uid) line (line 550, approx): void prng_write_seedfile(void) { int fd; char seed[1024]; char filename[1024]; struct passwd *pw; /* Don't bother if we have already saved a seed */ if (prng_seed_saved) return;

Hi, I just moved my cfservd (a part of sysutils/cfengine) from a 6.2 server to a 7.0 server. Ever since, cfservd crashes regularly. The backtrace is below, although obviously it is missing a lot. If anyone has clues or suggestions, I'd really appreciate it. # gdb /usr/local/sbin/cfservd cfservd.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc. GDB is free

One more bugfix since rc2: - Maildir: synchronization might have sometimes set wrong flags to messages, or crash completely Quite rare because we were lucky before :) And list of all the changes one more time: v0.99.10.5 2003-12-27 Timo Sirainen <tss at iki.fi> + MySQL authentication, patch by Matthew Reimer + --with-moduledir configure option - mbox: APPEND reversed given

I believe there is a problem with the openbsd-compat/bsd-arc4random.c file. If arc4random () is called without seed_rng having previously been called (eg if you run ssh-keygen -p ) then it does not in fact invoke seed_rng () if it is the first time. Instead it will invoke seed_rng every time BUT the first time. At least that is the way I read the code, and changing it as below allowed me to

Hi folks, I searched the list for LibreSSL and found only one mention of it! Has anyone gotten this working? I have it compiling no problem, but removing OpenSSL is another story of course. It seems to be compiled with FIPS support and of course there is no such thing in LibreSSL - that is something they tore out thanks, -Alan -- "Don't eat anything you've ever seen advertised
