Mandriva Linux Security Advisory 2013-039 - A null pointer de-reference flaw was found in the way Freetype font rendering engine handled Glyph bitmap distribution format fonts. A remote attacker could provide a specially-crafted BDF font file, which once processed in an application linked against FreeType would lead to that application crash. An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine performed parsing of glyph information and relevant bitmaps for glyph bitmap distribution format (BDF). A remote attacker could provide a specially-crafted BDF font file, which once opened in an application linked against FreeType would lead to that application crash. An out-of heap-based buffer write flaw was found in the way FreeType font rendering engine performed parsing of glyph information and relevant bitmaps for glyph bitmap distribution format (BDF). A remote attacker could provide a specially-crafted font file, which once opened in an application linked against FreeType would lead to that application crash, or, potentially, arbitrary code execution with the privileges of the user running the application.

Package : freetype2
Date : April 5, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated freetype2 packages fixes security vulnerabilities:

A null pointer de-reference flaw was found in the way Freetype font
rendering engine handled Glyph bitmap distribution format (BDF)
fonts. A remote attacker could provide a specially-crafted BDF font
file, which once processed in an application linked against FreeType
would lead to that application crash (CVE-2012-5668).

An out-of heap-based buffer read flaw was found in the way FreeType
font rendering engine performed parsing of glyph information and
relevant bitmaps for glyph bitmap distribution format (BDF). A remote
attacker could provide a specially-crafted BDF font file, which once
opened in an application linked against FreeType would lead to that
application crash (CVE-2012-5669).

An out-of heap-based buffer write flaw was found in the way FreeType
font rendering engine performed parsing of glyph information and
relevant bitmaps for glyph bitmap distribution format (BDF). A remote
attacker could provide a specially-crafted font file, which once
opened in an application linked against FreeType would lead to that
application crash, or, potentially, arbitrary code execution with
the privileges of the user running the application (CVE-2012-5670).
