Name of the Vulnerable Software and Affected Versions
libexif versions prior to 0.6.21
libexif-0.6.21
libexif-devel versions prior to 0.6.21
libexif-64bit versions prior to 0.6.21
libexif-32bit versions prior to 0.6.21
libexif-debuginfo-0.6.21
Description
The issue concerns multiple vulnerabilities in the libexif package, which can lead to a disruption of confidentiality, integrity, and availability of protected information. These vulnerabilities can be exploited remotely, potentially allowing attackers to cause a denial of service or execute arbitrary code via crafted EXIF tags in an image. The exif entry format value function in exif-entry.c in the EXIF Tag Parsing Library is specifically affected by a buffer overflow.
Recommendations
For libexif versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-0.6.21, update to a version later than 0.6.21.
For libexif-devel versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-64bit versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-32bit versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-debuginfo-0.6.21, update to a version later than 0.6.21.
As a temporary workaround, consider disabling the
exif entry format value function until a patch is available. Restrict access to the vulnerable libexif module to minimize the risk of exploitation. Avoid using crafted EXIF tags in images until the issue is resolved.Correção
