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 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`). The bug is fixed in version v0.27.5.

An infinite loop is triggered when Exiv2 is used to read the metadata of a crafted image\n file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can\n trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.5.\n (CVE-2021-34334)\n\n - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata\n of image files. A floating point exception (FPE) due to an integer divide by zero was found in Exiv2\n versions v0.27.4 and earlier. The FPE is triggered when Exiv2 is used to print the metadata of a crafted\n image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they\n can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when\n printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires\n an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5. (CVE-2021-34335)\n\n - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata\n of image files. A null pointer dereference was found in Exiv2 versions v0.27.4 and earlier. The null\n pointer dereference is triggered when Exiv2 is used to print the metadata of a crafted image file. An\n attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the\n victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the\n interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra\n command line option (`-p t` or `-P t`).

An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds\n read is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could\n potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into\n running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the image ICC\n profile, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p\n C`). The bug is fixed in version v0.27.5. (CVE-2021-37618)\n\n - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata\n of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds\n read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could\n potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick\n the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing\n the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to\n trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such\n as insert. The bug is fixed in version v0.27.5.

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 (CVE-2021-37615, CVE-2021-37616). 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 print the metadata of a crafted image file. An attacker could potentially exploit thevulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file (CVE-2021-37618, CVE-2021-37619, CVE-2021-37620). 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 (CVE-2021-37621, CVE-2021-37622, CVE-2021-37623). \n", "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "baseScore": 5.5, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 3.6}, "published": "2021-09-04T17:01:38", "type": "mageia", "title": "Updated exiv2 packages fix security vulnerabilities\n", "bulletinFamily": "unix", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "NONE", "availabilityImpact": "PARTIAL", "integrityImpact": "NONE", "baseScore": 4.3, "vectorString": "AV:N/AC:M/Au:N/C:N/I:N/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 2.9, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2021-32815", "CVE-2021-34334", "CVE-2021-34335", "CVE-2021-37615", "CVE-2021-37616", "CVE-2021-37618", "CVE-2021-37619", "CVE-2021-37620", "CVE-2021-37621", "CVE-2021-37622", "CVE-2021-37623"], "modified": "2021-09-04T17:01:38", "id": "MGASA-2021-0415", "href": "https://advisories.mageia.org/MGASA-2021-0415.html", "cvss": {"score": 4.3, "vector": "AV:N/AC:M/Au:N/C:N/I:N/A:P"}}], "fedora": [{"lastseen": "2023-05-27T14:49:26", "description": "MinGW Windows exiv2 library.
