I had not checked the US-Cert alerts in awhile, and today found this (the alert came out last week in Feb., I believe):

The mime_hdr_cmp function in crypto/asn1/asn_mime.c
in OpenSSL 0.9.8t and earlier allows remote attackers to
cause a denial of service (NULL pointer dereference and
application crash) via a crafted S/MIME message.

How do I find out what version of OpenSSL is in use on, for example, Firefox? The Cert alert includes a patch, but I prefer to first find out whether I need it.

Thanks for any response/suggestion.

Use the version option.

$ openssl version
OpenSSL 0.9.8b 04 May 2006
You can get much more information with the version -a option.

$ openssl version -a
OpenSSL 0.9.8b 04 May 2006
built on: Fri Sep 29 18:45:58 UTC 2006
platform: debian-i386-i686/cmov
options: bn(64,32) md2(int) rc4(idx,int) des(ptr,risc1,16,long) blowfish(idx)
compiler: gcc -fPIC -DOPENSSL_PIC -DZLIB -DOPENSSL_THREADS -D_REENTRANT
-DDSO_DLFCN -DHAVE_DLFCN_H -DL_ENDIAN -DTERMIO -O3 -march=i686
-Wa,--noexecstack -g -Wall -DOPENSSL_BN_ASM_PART_WORDS -DOPENSSL_IA32_SSE2
-DSHA1_ASM -DMD5_ASM -DRMD160_ASM -DAES_ASM
OPENSSLDIR: "/usr/lib/ssl"

Hope the above suggestions could help you.
