Need Pointers on Cores.

["Ramapandi Muniyasamy -X (ramapmun - WIPRO LIMITED at Cisco)" <ra...@cisco.com>]

Hi All,

I am getting a crash when I am newly migrating to openssl 1.1.1l with version 2.4.39

I see below, in the bio_filter_out_method structure is corrupted when checked in free_bio_methods function frame below.

gdb) bt
#0 0x77baf875 in free () from /lib/libc.so.6
#1 0x77ea6eff in CRYPTO_free (str=0x3, file=0x77f55825 "crypto/bio/bio_meth.c", line=53) at crypto/mem.c:312

#8 0x08076197 in destroy_and_exit_process ()
#9 0x08077d3a in main ()
(gdb)

Any pointers on what could be the issue and whether any patch is fixing this issue?

My configuration is

apache: 2.4.39
apr-1.5.2
apr-util-1.5.4
OpenSSL 1.1.1l


Thanks,

You need to re-build httpd with the new openssl (./configure
--with-openssl=/path/to/openssl 1.1.1l ...), and verify that httpd is
linked to the new openssl at runtime (`ldd modules/mod_ssl.so` should
show the new paths for openssl, and/or LD_LIBRARY_PATH should be
used).


Regards;
Yann.
