Mandriva Linux Security Advisory 2012-106 - A heap-based out-of-bounds array read in the exif_entry_get_value function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags. A heap-based out-of-bounds array read in the exif_convert_utf16_to_utf8 function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags. Various other issues have also been addressed.

Package : libexif
Date : July 13, 2012
Affected: 2011., Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in libexif:

A heap-based out-of-bounds array read in the exif_entry_get_value
function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows
remote attackers to cause a denial of service or possibly obtain
potentially sensitive information from process memory via an image
with crafted EXIF tags (CVE-2012-2812).

A heap-based out-of-bounds array read in the exif_convert_utf16_to_utf8
function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows
remote attackers to cause a denial of service or possibly obtain
potentially sensitive information from process memory via an image
with crafted EXIF tags (CVE-2012-2813).

A buffer overflow in the exif_entry_format_value function in
libexif/exif-entry.c in libexif 0.6.20 allows remote attackers to
cause a denial of service or possibly execute arbitrary code via an
image with crafted EXIF tags (CVE-2012-2814).

A heap-based out-of-bounds array read in the exif_data_load_data
function in libexif 0.6.20 and earlier allows remote attackers to
cause a denial of service or possibly obtain potentially sensitive
information from process memory via an image with crafted EXIF tags
(CVE-2012-2836).

A divide-by-zero error in the mnote_olympus_entry_get_value function
while formatting EXIF maker note tags in libexif 0.6.20 and earlier
allows remote attackers to cause a denial of service via an image
with crafted EXIF tags (CVE-2012-2837).

An off-by-one error in the exif_convert_utf16_to_utf8 function in
libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote
attackers to cause a denial of service or possibly execute arbitrary
code via an image with crafted EXIF tags (CVE-2012-2840).

An integer underflow in the exif_entry_get_value function can cause a
heap overflow and potentially arbitrary code execution while formatting
an EXIF tag, if the function is called with a buffer size parameter
equal to zero or one (CVE-2012-2841).

The updated packages have been upgraded to the 0.6.21 version which
is not vulnerable to these issues.
