Fedora alert FEDORA-2012-3536 (libpng10)
-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2012-3536 2012-03-10 21:24:09 -------------------------------------------------------------------------------- Name : libpng10 Product : Fedora 15 Version : 1.0.58 Release : 1.fc15 URL : http://www.libpng.org/pub/png/libpng.html Summary : Old version of libpng, needed to run old binaries Description : The libpng10 package contains an old version of libpng, a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. This package is needed if you want to run binaries that were linked dynamically with libpng 1.0.x. -------------------------------------------------------------------------------- Update Information: A type conversion flaw leading to an out-of-bounds heap buffer read was found in the way libpng10, a library of functions for manipulation PNG image format files, performed expansion of certain iCCP, iTXt, and zTXt PNG image file chunks. A remote attacker could provide a specially-crafted Portable Network Graphics (PNG) image file, which once opened in an application, linked against libpng10, could lead to denial of service or in some cases, execution of arbitrary code without permission of the user running such an application. -------------------------------------------------------------------------------- ChangeLog: * Fri Mar 9 2012 Paul Howarth <paul@city-fan.org> 1.0.58-1 - update to 1.0.58 - fix bug with png_handle_hIST with odd chunk length - fix incorrect type (int copy should be png_size_t copy) in png_inflate() (CVE-2011-3045) - fix off-by-one bug in png_handle_sCAL() when using fixed point arithmetic, causing out-of-bounds read in png_set_sCAL() because of failure to copy the string terminators - remove the png_free() of unused png_ptr->current_text from pngread.c - remove all of the assembler code from pnggccrd.c and just "return 2;" * Sun Feb 19 2012 Paul Howarth <paul@city-fan.org> 1.0.57-1 - update to 1.0.57 (fixed CVE-2011-3026 buffer overrun bug) * Thu Jan 5 2012 Paul Howarth <paul@city-fan.org> 1.0.56-2 - rebuilt for gcc 4.7 * Sat Jul 9 2011 Paul Howarth <paul@city-fan.org> 1.0.56-1 - update to 1.0.56 - fix regression in Makefile.am/Makefile.in - fix "make distcheck" - drop upstreamed fix for libpng.sym build failure * Thu Jul 7 2011 Paul Howarth <paul@city-fan.org> 1.0.55-1 - update to 1.0.55 - fixed uninitialized memory read in png_format_buffer() (CVE-2011-2501, related to CVE-2004-0421) - pass "" instead of '\0' to png_default_error() in png_err() (CVE-2011-2691) - check for up->location !PNG_AFTER_IDAT when writing unknown chunks before IDAT - ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image, always expand to RGBA if transparency is present - check for integer overflow in png_set_rgb_to_gray() (CVE-2011-2690) - check for sCAL chunk too short (CVE-2011-2692) - drop upstreamed patch for CVE-2011-2501 - add patch to fix build failure due to regression in libpng.sym creation * Wed Jun 29 2011 Paul Howarth <paul@city-fan.org> 1.0.54-3 - fix 1-byte uninitialized memory reference in png_format_buffer() (CVE-2011-2501, related to CVE-2004-0421) - nobody else likes macros for commands -------------------------------------------------------------------------------- References: [ 1 ] Bug #799000 - CVE-2011-3045 libpng: buffer overflow in png_inflate caused by invalid type conversions https://bugzilla.redhat.com/show_bug.cgi?id=799000 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
