-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : libpng SUMMARY : Buffer overflow vulnerability DATE : 2003-01-23 18:17:00 ID : CLA-2003:564 RELEVANT RELEASES : 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION libpng is a library used to create and manipulate PNG (Portable Network Graphics) image files. Glenn Randers-Pehrson discovered a buffer overflow vulnerability in unpatched libpng versions prior to 1.0.15 and 1.2.5(*) (inclusive). Programs such as web browsers and various others common applications make use of libpng. An attacker could exploit this vulnerability to remotely run arbitrary code or crash such applications by using a specially crafted png image. This update provides patched versions of libpng with fixes for this vulnerability. * The libpng-1.2.X series is available only in Conectiva Linux 8 in the libpng3 package. SOLUTION All users should upgrade. Please note that in order to complete the upgrade process, you must restart all running aplications that are linked against libpng after the new packages installation. You can see a list of such applications using the lsof utility, as seen below: # lsof | grep libpng REFERENCES: 1.http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1363 UPDATED PACKAGES ftp://atualizacoes.conectiva.com.br/6.0/RPMS/libpng-1.0.14-1U60_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/RPMS/libpng-devel-1.0.14-1U60_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/SRPMS/libpng-1.0.14-1U60_2cl.src.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/libpng-1.0.14-1U70_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/libpng-devel-1.0.14-1U70_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/libpng-devel-static-1.0.14-1U70_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/libpng-doc-1.0.14-1U70_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/SRPMS/libpng-1.0.14-1U70_2cl.src.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/libpng-1.0.14-1U80_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/libpng3-1.2.4-1U80_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/libpng-devel-1.2.4-1U80_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/libpng-devel-static-1.2.4-1U80_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/libpng-doc-1.2.4-1U80_2cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/SRPMS/libpng-1.0.14-1U80_2cl.src.rpm ftp://atualizacoes.conectiva.com.br/8/SRPMS/libpng3-1.2.4-1U80_2cl.src.rpm ADDITIONAL INSTRUCTIONS Users of Conectiva Linux version 6.0 or higher may use apt to perform upgrades of RPM packages: - run: apt-get update - after that, execute: apt-get upgrade Detailed instructions reagarding the use of apt and upgrade examples can be found at http://distro.conectiva.com.br/atualizacoes/#apt?idioma=en - ------------------------------------------------------------------------- All packages are signed with Conectiva's GPG key.
