In libexif through 0.6.25, an integer underflow in size checking for Fuji and Olympus MakerNote decoding could be used by attackers to crash or leak information out of libexif-using programs.
In libexif through 0.6.25, an unsigned 32bit integer overflow in Nikon MakerNote handling could be used by local attackers to cause crashes or information leaks. This only affects 32bit systems.

In exifdataloaddatacontent of exif-data.c, there is a possible UBSAN abort due to an integer overflow. This could lead to remote denial of service with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-146428941
An issue was discovered in libexif before 0.6.22. Use of uninitialized memory in EXIF Makernote handling could lead to crashes and potential use-after-free conditions.
An issue was discovered in libexif before 0.6.22. Several buffer over-reads in EXIF MakerNote handling could lead to information disclosure and crashes. This is different from CVE-2020-0093.
An issue was discovered in libexif before 0.6.22. An unrestricted size in handling Canon EXIF MakerNote data could lead to consumption of large amounts of compute time for decoding EXIF data.
exifentrygetvalue in exif-entry.c in libexif 0.6.21 has a divide-by-zero error.
In exifdatasavedataentry of exif-data.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9 Android-10Android ID: A-148705132
An error when processing the EXIFIFDINTEROPERABILITY and EXIFIFDEXIF tags within libexif version 0.6.21 can be exploited to exhaust available CPU resources.
A vulnerability was found in libexif. An integer overflow when parsing the MNOTE entry data of the input file. This can cause Denial-of-Service (DoS) and Information Disclosure (disclosing some critical heap chunk metadata, even other applications' private data).

The mnoteolympusentrygetvalue function in olympus/mnote-olympus-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service (divide-by-zero error) via an image with crafted EXIF tags that are not properly handled during the formatting of EXIF maker note tags.
Integer underflow in the exifentrygetvalue function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 might allow remote attackers to execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
The exifdataloaddata function in exif-data.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory via crafted EXIF tags in an image.
Off-by-one error in the exifconvertutf16toutf8 function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted EXIF tags in an image.
Buffer overflow in the exifentryformatvalue function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted EXIF tags in an image.
The exifentrygetvalue function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory via crafted EXIF tags in an image.
The exifconvertutf16toutf8 function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory via crafted EXIF tags in an image.
An infinite recursion flaw was found in libexif. This could be leveraged by an attacker to crash an application using libexif to process image data content.
