OpenSSL Vulnerabilities

Here's how I do it [line may wrap]:

for i in /bin/* /usr/bin/* /sbin/* /usr/sbin/* /usr/X11R6/bin/* /usr/local/bin/* ; do if ldd $i | egrep 'libssl' > /dev/null ; then echo $i ; fi ; done

You could change the list of directories you want to search, or use
the output of a find in the for command. I don't think libcrypto has
issues; if it does, make the argument to egrep
'libcrypto|libssl'.

And

# lsof | egrep 'libcrypto|libssl'

or shorter

# lsof | egrep 'libcrypto|libssl' | awk '{ print$1 }' | sort | uniq

gives an overview, which current running processes must be restarted
afer updating the libraries (and calling ldconfig).

IMHO the general problem is recompiling progs which use OpenSSL statically

Are you aware of any such programs?
