Summary

Stack-based buffer overflow in the cf2_hintmap_build function in cff/cf2hints.c in FreeType before 2.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of stem hints in a font file.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionUpdated freetype2 packages fix security vulnerabilities : It was reported that Freetype before 2.5.3 suffers from an out-of-bounds stack-based read/write flaw in cf2_hintmap_build() in the CFF rasterizing code, which could lead to a buffer overflow (CVE-2014-2240). It was also reported that Freetype before 2.5.3 has a denial-of-service vulnerability in the CFF rasterizing code, due to a reachable assertion (CVE-2014-2241). It was reported that Freetype before 2.5.4 suffers from an out-of-bounds stack-based read/write flaw in cf2_hintmap_build() in the CFF rasterizing code, which could lead to a buffer overflow. This is due to an incomplete fix for CVE-2014-2240. The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 does not properly check for an integer overflow, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType font (CVE-2014-9656). The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font (CVE-2014-9657). The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4enforces an incorrect minimum table length, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font (CVE-2014-9658). The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font (CVE-2014-9660). type42/t42parse.c in FreeType before 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font (CVE-2014-9661). cff/cf2ft.c in FreeType before 2.5.4 does not validate the return values of point-allocation functions, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted OTF font (CVE-2014-9662). The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field
