Summary

libexif through 0.6.21 is vulnerable to out-of-bounds heap read vulnerability in exif_data_save_data_entry function in libexif/exif-data.c caused by improper length computation of the allocated data of an ExifMnote entry which can cause denial-of-service or possibly information disclosure.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
