CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-37621 – Denial of service due to infinite loop in Image::printIFDStructure
https://notcve.org/view.php?id=CVE-2021-37621
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 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 image ICC profile, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p C`). • https://github.com/Exiv2/exiv2/pull/1778 https://github.com/Exiv2/exiv2/security/advisories/GHSA-m479-7frc-gqqg 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') •

https://notcve.org/view.php?id=CVE-2021-32617
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An inefficient algorithm (quadratic complexity) was found in Exiv2 versions v0.27.3 and earlier. The inefficient algorithm 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, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4. • https://github.com/Exiv2/exiv2/pull/1657 https://github.com/Exiv2/exiv2/security/advisories/GHSA-w8mv-g8qq-36mj https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5I3RRZUGSBIUYZ5TIHLN55PKMAWCSJ5G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M2BPQNJKTRIDINTVJ22QMMTIZEPHVKXK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RQAKFIQHW2AS3AGSJM42ABOA6CWIJBGM https://lists.fedoraproject.org/archives/list/package-a • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2021-29623
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A read of uninitialized memory was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack memory, if they can trick the victim into running Exiv2 on a crafted image file. • https://github.com/Exiv2/exiv2/pull/1627 https://github.com/Exiv2/exiv2/security/advisories/GHSA-6253-qjwm-3q4v https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5I3RRZUGSBIUYZ5TIHLN55PKMAWCSJ5G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M2BPQNJKTRIDINTVJ22QMMTIZEPHVKXK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RQAKFIQHW2AS3AGSJM42ABOA6CWIJBGM https://lists.fedoraproject.org/archives/list/package-a • CWE-908: Use of Uninitialized Resource •

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 v0.27.3 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/commit/783b3a6ff15ed6f82a8f8e6c8a6f3b84a9b04d4b https://github.com/Exiv2/exiv2/security/advisories/GHSA-5p8g-9xf3-gfrr https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K3HKXR6JOVKMBE4HY4FDXNVZGNCQG6T3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NDMZTVQAZSMLPTDVDYLBHAAF7I5QXVYQ https://security.gentoo.org/glsa/202312-06 https://access.redhat.com/security/cve/CVE-2021-29463 https://bugzilla.redhat.com/show_bug&# • CWE-125: Out-of-bounds Read •
