 Mandriva Linux Security Advisory                         MDVSA-2013:035
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

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

 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.
