CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-37615 – Null pointer dereference in Exiv2::Internal::resolveLens0x319
https://notcve.org/view.php?id=CVE-2021-37615
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-h9x9-4f77-336w 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 •

https://notcve.org/view.php?id=CVE-2021-37619
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. • https://github.com/Exiv2/exiv2/pull/1752 https://github.com/Exiv2/exiv2/security/advisories/GHSA-mxw9-qx4c-6m8v 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://access.redhat.com/security/cve/CVE-2021-37619 https://bugzilla.redhat.com/show_bug.cgi?id=1992174 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2021-37623
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An infinite loop was found in Exiv2 versions v0.27.4 and earlier. The infinite loop 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 deleting the IPTC data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-d I rm`). • https://github.com/Exiv2/exiv2/pull/1790 https://github.com/Exiv2/exiv2/security/advisories/GHSA-mvc4-g5pv-4qqq 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-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
