This bug was fixed in the package openssl - 1.0.1-4ubuntu1
---------------
openssl (1.0.1-4ubuntu1) precise; urgency=low
* Resynchronise with Debian (LP: #968753). Remaining changes:
- debian/libssl1.0.0.postinst:
+ Display a system restart required notification on libssl1.0.0
upgrade on servers.
+ Use a different priority for libssl1.0.0/restart-services depending
on whether a desktop, or server dist-upgrade is being performed.
- debian/{libssl1.0.0-udeb.dirs, control, rules}: Create
libssl1.0.0-udeb, for the benefit of wget-udeb (no wget-udeb package
in Debian).
- debian/{libcrypto1.0.0-udeb.dirs, libssl1.0.0.dirs, libssl1.0.0.files,
rules}: Move runtime libraries to /lib, for the benefit of
wpasupplicant.
- debian/patches/perlpath-quilt.patch: Don't change perl #! paths under
.pc.
- debian/rules:
+ Don't run 'make test' when cross-building.
+ Use host compiler when cross-building. Patch from Neil Williams.
+ Don't build for processors no longer supported: i586 (on i386)
+ Fix Makefile to properly clean up libs/ dirs in clean target.
+ Replace duplicate files in the doc directory with symlinks.
- Unapply patch c_rehash-multi and comment it out in the series as it
breaks parsing of certificates with CRLF line endings and other cases
(see Debian #642314 for discussion), it also changes the semantics of
c_rehash directories by requiring applications to parse hash link
targets as files containing potentially *multiple* certificates rather
than exactly one.
- Bump version passed to dh_makeshlibs to 1.0.1 for new symbols.
- Experimental workaround to large client hello issue: if
OPENSSL_NO_TLS1_2_CLIENT is set then TLS v1.2 is disabled for clients
only.
- Compile with -DOPENSSL_NO_TLS1_2_CLIENT.
openssl (1.0.1-4) unstable; urgency=low
* Use official patch for the vpaes problem, also covering amd64.
openssl (1.0.1-3) unstable; urgency=high
* Fix crash in vpaes (Closes: #665836)
* use client version when deciding whether to send supported signature
