Trustix Secure Linux Advisory: openssl

Feb 22, 2003, 12:59 (0 Talkback[s])

- --------------------------------------------------------------------------
Trustix Secure Linux Security Advisory #2003-0005

Package name:      openssl
Summary:           Security fix
Date:              2003-02-20
Affected versions: TSL 1.1, 1.2, 1.5

- --------------------------------------------------------------------------
Package description:
  A C library that provides various crytographic algorithms and protocols,
  including DES, RC4, RSA, and SSL. Includes shared libraries.
  

Problem description:
  From the openssl advisory:
  OpenSSL version since 0.9.6c supposedly treat block cipher padding
  errors like MAC verification errors during record decryption
  (see http://www.openssl.org/~bodo/tls-cbc.txt), but MAC verification
  was still skipped after detection of a padding error, which allowed
  the timing attack.  (Note that it is likely that other SSL/TLS
  implementations will have similar problems.)

  OpenSSL 0.9.6i and 0.9.7a perform a MAC computation even if incorrrect
  block cipher padding has been found to minimize information leaked via
  timing.  For earlier versions starting with 0.9.6e, the enclosed
  security patch can be used.


Action:
  We recommend that all systems with this package installed be upgraded.


Location:
  All TSL updates are available from
  <URI:http://www.trustix.net/pub/Trustix/updates/>;
  <URI:ftp://ftp.trustix.net/pub/Trustix/updates/>


About Trustix Secure Linux:
  Trustix Secure Linux is a small Linux distribution for servers. With focus
  on security and stability, the system is painlessly kept safe and up to
  date from day one using swup, the automated software updater.


Automatic updates:
  Users of the SWUP tool can enjoy having updates automatically
  installed using 'swup --upgrade'.

  Get SWUP from:
  <URI:ftp://ftp.trustix.net/pub/Trustix/software/swup/>


Public testing:
  These packages have been available for public testing for some time.
  If you want to contribute by testing the various packages in the
  testing tree, please feel free to share your findings on the
  tsl-discuss mailinglist.
  The testing tree is located at
