CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-37616 – Null pointer dereference in Exiv2::Internal::resolveLens0x8ff
https://notcve.org/view.php?id=CVE-2021-37616
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A null pointer dereference was found in Exiv2 versions v0.27.4 and earlier. The null pointer dereference is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). • https://github.com/Exiv2/exiv2/pull/1758 https://github.com/Exiv2/exiv2/security/advisories/GHSA-54f7-vvj7-545w https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FMDT4PJB7P43WSOM3TRQIY3J33BAFVVE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UYGDELIFFJWKUU7SO3QATCIXCZJERGAC https://security.gentoo.org/glsa/202312-06 • CWE-476: NULL Pointer Dereference •
CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-32815 – Denial of service due to assertion failure in crwimage_int.cpp
https://notcve.org/view.php?id=CVE-2021-32815
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The assertion failure is triggered when Exiv2 is used to modify the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when modifying the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `fi`. ### Patches The bug is fixed in version v0.27.5. ### References Regression test and bug fix: #1739 ### For more information Please see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security. • https://github.com/Exiv2/exiv2/pull/1739 https://github.com/Exiv2/exiv2/security/advisories/GHSA-mv9g-fxh2-m49m https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FMDT4PJB7P43WSOM3TRQIY3J33BAFVVE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UYGDELIFFJWKUU7SO3QATCIXCZJERGAC https://security.gentoo.org/glsa/202312-06 • CWE-617: Reachable Assertion •

CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 1CVE-2021-31292 – exiv2: Integer overflow in CrwMap:encode0x1810 leading to heap-based buffer overflow and DoS
https://notcve.org/view.php?id=CVE-2021-31292
An integer overflow in CrwMap::encode0x1810 of Exiv2 0.27.3 allows attackers to trigger a heap-based buffer overflow and cause a denial of service (DOS) via crafted metadata. Un desbordamiento de enteros en la función CrwMap::encode0x1810 de Exiv2 versión 0.27.3 permite a atacantes desencadenar un desbordamiento del búfer en la región heap de la memoria y causar una denegación de servicio (DOS) por medio de metadatos diseñados A flaw was found in exiv2. A integer wraparound in the CrwMap:encode0x1810 function leads to memcpy call with a very large size allowing an attacker, who can provide a malicious image, to crash an application which uses the exiv2 library. The highest threat from this vulnerability is to service availability. • https://github.com/Exiv2/exiv2/issues/1530 https://lists.debian.org/debian-lts-announce/2021/08/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FMDT4PJB7P43WSOM3TRQIY3J33BAFVVE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UYGDELIFFJWKUU7SO3QATCIXCZJERGAC https://security.gentoo.org/glsa/202312-06 https://www.debian.org/security/2021/dsa-4958 https://access.redhat.com/security/cve/CVE-2021-31292 https:/&#x • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
