openSUSE Security Update: update for putty

Announcement ID: openSUSE-SU-2013:1355-1
Rating: moderate
References: #833567
Cross-References: CVE-2013-4852
Affected Products:
openSUSE 12.3

An update that fixes one vulnerability is now available.


Putty was updated to 0.63, bringing features, bug and
security fixes.

- Add 0001-Revert-the-default-for-font-bolding-style.patch
(upstream patch fixing a cosmetic change introduced in
- Add Conflict tag against pssh package (Parallel SSH) due
to conflicting files in /usr/bin

- Do signature verification

- update to 0.63
* Security fix: prevent a nefarious SSH server or network
attacker from crashing PuTTY at startup in three
different ways by presenting a maliciously constructed
public key and signature. [bnc#833567] CVE-2013-4852
* Security fix: PuTTY no longer retains the private half
of users' keys in memory by mistake after
authenticating with them.
* Revamped the internal configuration storage system to
remove all fixed arbitrary limits on string lengths.
In particular, there should now no longer be an
unreasonably small limit on the number of port
forwardings PuTTY can store.
* Forwarded TCP connections which close one direction
before the other should now be reliably supported, with
EOF propagated independently in the two directions.
This also fixes some instances of forwarding data
corruption (if the corruption consisted of losing data
from the very end of the connection) and some instances
of PuTTY failing to close when the session is over
(because it wrongly thought a forwarding channel was
still active when it was not).
* The terminal emulation now supports xterm's bracketed
paste mode (allowing aware applications to tell the
difference between typed and pasted text, so that e.g.
editors need not apply inappropriate auto-indent).
* You can now choose to display bold text by both
brightening the foreground colour and changing the
font, not just one or the other.
* PuTTYgen will now never generate a 2047-bit key when
asked for 2048 (or more generally n−1 bits when asked
for n).
* Some updates to default settings: PuTTYgen now
generates 2048-bit keys by default (rather than 1024),
and PuTTY defaults to UTF-8 encoding and 2000 lines of
scrollback (rather than ISO 8859-1 and 200).
* Unix: PSCP and PSFTP now preserve the Unix file
permissions, on copies in both directions.
* Unix: dead keys and compose-character sequences are now
* Unix: PuTTY and pterm now permit font fallback (where
glyphs not present in your selected font are
automatically filled in from other fonts on the
system) even if you are using a server-side X11 font
rather than a Pango client-side one.
* Bug fixes too numerous to list, mostly resulting from
running the code through Coverity Scan which spotted
an assortment of memory and resource leaks, logic
errors, and crashes in various circumstances.
- packaging changes:
* run make from base directory
* run tests
* remove putty-01-werror.diff (currently not needed)
* remove putty-02-remove-gtk1.diff,
putty-06-gtk2-indivhdr.diff (no longer needed)
* refresh putty-03-config.diff
* remove autoconf calls and requirements
* package HTML documentation
* package LICENCE file
