HighCVSS 7.1 EPSS 0.10%
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.
-
HighCVSS 7.8 EPSS 0.22%
libexif through 0.6.25 has a flaw in decoding MakerNotes. If the exif_mnote_data_get_value function gets passed in a 0 size, the passed in-buffer would be overwritten due to an integer underflow.
-
MediumCVSS 5.5 EPSS 1.3%
NULL Pointer Deference in the exif command line tool, when printing out XML formatted EXIF data, in exif v0.6.22 and earlier allows attackers to cause a Denial of Service (DoS) by uploading a malicious JPEG file, causing the application to crash.

HighCVSS 8.2 EPSS 1.9%
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.
-
CriticalCVSS 9.1 EPSS 2.8%
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.
-
HighCVSS 7.5 EPSS 2.4%
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.
