CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-29464 – Heap buffer overflow in Exiv2::Jp2Image::encodeJp2Header
https://notcve.org/view.php?id=CVE-2021-29464
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/commit/f9308839198aca5e68a65194f151a1de92398f54 https://github.com/Exiv2/exiv2/security/advisories/GHSA-jgm9-5fw5-pw9p 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-2021-29464 https://bugzilla.redhat.com/show_bug&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •
