An out-of heap-based buffer read flaw was found in the way auxiliary PostScript driver of the FreeType font rendering engine performed conversion of certain PostScript font objects. A remote attacker could provide a specially-crafted PostScript font file, which once opened 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 TrueType bytecode / opcode interpreter of FreeType font rendering engine executed the 'Move Indirect Relative Point' (MIRP) instruction. 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.

An out-of heap-based buffer read flaw was found in the way the anti-aliasing renderer of the FreeType font rendering engine processed certain TrueType fonts. A remote attacker could provide a specially-crafted TrueType font file, which once opened 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 Type42 font parser of the FreeType font rendering engine performed parsing of certain special font name table (SFNT) strings. 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.

A NULL pointer dereference flaw as found in the way TrueType bytecode interpreter of the FreeType font rendering engine performed movement of the zone2 pointer point for certain TrueType fonts. A remote attacker could provide a specially-crafted TrueType font file, which once opened in an application linked against FreeType would lead to that application crash.
