An error when processing the EXIF_IFD_INTEROPERABILITY and EXIF_IFD_EXIF tags within libexif version 0.6.21 can be exploited to exhaust available CPU resources.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An error when processing the EXIF_IFD_INTEROPERABILITY and EXIF_IFD_EXIF tags within libexif version     0.6.21 can be exploited to exhaust available CPU resources. (CVE-2018-20030)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14294-1 advisory.

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

CVE-2018-20030

This issue had already been addressed via DLA-2214-1. However, upstream provided an updated patch, so this has been followed up on.

CVE-2020-13112

Several buffer over-reads in EXIF MakerNote handling could have lead to information disclosure and crashes. This issue is different from already resolved CVE-2020-0093.

CVE-2020-13113

Use of uninitialized memory in EXIF Makernote handling could have lead to crashes and potential use-after-free conditions.

CVE-2020-13114

An unrestricted size in handling Canon EXIF MakerNote data could have lead to consumption of large amounts of compute time for decoding EXIF data.

For Debian 8 'Jessie', these problems have been fixed in version 0.6.21-2+deb8u3.

We recommend that you upgrade your libexif packages.

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.

According to the versions of the libexif package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Most digital cameras produce EXIF files, which are JPEG     files with extra tags that contain information about     the image. The EXIF library allows you to parse an EXIF     file and read the data from those tags.

  - Security fix(es):

  - An error when processing the EXIF_IFD_INTEROPERABILITY     and EXIF_IFD_EXIF tags within libexif version 0.6.21     can be exploited to exhaust available CPU     resources.(CVE-2018-20030)
