New libexif packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix security issues.

Various vulnerabilities have been addressed in libexif, a library to parse EXIF metadata files.

CVE-2016-6328

An integer overflow when parsing the MNOTE entry data of the input file had been found. This could have caused denial of service (DoS) and Information Disclosure (disclosing some critical heap chunk metadata, even other applications' private data).

CVE-2017-7544

libexif had been 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 could have caused denial of service or possibly information disclosure.

CVE-2018-20030

An error when processing the EXIF_IFD_INTEROPERABILITY and EXIF_IFD_EXIF tags within libexif version could have been exploited to exhaust available CPU resources.

CVE-2020-0093

In exif_data_save_data_entry of exif-data.c, there was a possible out of bounds read due to a missing bounds check. This could have lead to local information disclosure with no additional execution privileges needed. User interaction was needed for exploitation.

CVE-2020-12767

libexif had a divide-by-zero error in exif_entry_get_value in exif-entry.c

For Debian 8 'Jessie', these problems have been fixed in version 0.6.21-2+deb8u2.

We recommend that you upgrade your libexif packages.
