Multiple vulnerabilities has been found and corrected in freetype2: The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted font file . Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow . FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted font file . Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File font . bdf/bdflib.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service via a crafted BDF font file, related to an attempted modification of a value in a static string . The updated packages have been patched to correct these issues.
