| Description: | From the Mandriva advisory:
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). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
