https://notcve.org/view.php?id=CVE-2021-29473
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds read 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 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. • https://github.com/Exiv2/exiv2/security/advisories/GHSA-7569-phvm-vwc2 https://github.com/Exiv2/exiv2/security/policy https://github.com/github/advisory-review/pull/1587 https://lists.debian.org/debian-lts-announce/2021/08/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQT5F5IINTDYDAFGVGQZ7PMMLG7I5ZZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JWZLDECIXXW3CCZ3RS4A3NG5X5VE4WZM https://lists.fedoraproject.org/archi • CWE-125: Out-of-bounds Read •

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, 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/issues/1529 https://github.com/Exiv2/exiv2/pull/1534 https://github.com/Exiv2/exiv2/security/advisories/GHSA-v74w-h496-cgqm https://lists.debian.org/debian-lts-announce/2021/08/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQT5F5IINTDYDAFGVGQZ7PMMLG7I5ZZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2A5GMJEXQ5Q76JK6F6VKK5JYCLVFGKN https://security.gentoo.org/glsa/202312-06 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
