CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-34335 – Denial of service due to FPE in Exiv2::Internal::resolveLens0xffff
https://notcve.org/view.php?id=CVE-2021-34335
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A floating point exception (FPE) due to an integer divide by zero was found in Exiv2 versions v0.27.4 and earlier. The FPE 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/1750 https://github.com/Exiv2/exiv2/security/advisories/GHSA-pvjp-m4f6-q984 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-369: Divide By Zero •
CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-34334 – Denial of service due to integer overflow in loop counter
https://notcve.org/view.php?id=CVE-2021-34334
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An infinite loop is triggered when Exiv2 is used to read 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. The bug is fixed in version v0.27.5. Exiv2 es una utilidad de línea de comandos y una biblioteca C++ para leer, escribir, borrar y modificar los metadatos de los archivos de imagen. • https://github.com/Exiv2/exiv2/pull/1766 https://github.com/Exiv2/exiv2/security/advisories/GHSA-hqjh-hpv8-8r9p 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-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
