CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-29463 – Out-of-bounds read in Exiv2::WebPImage::doWriteMetadata
https://notcve.org/view.php?id=CVE-2021-29463
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 •

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 •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 1CVE-2020-18032 – graphviz: off-by-one in parse_reclbl() in lib/common/shapes.c
https://notcve.org/view.php?id=CVE-2020-18032
Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted file into the "lib/common/shapes.c" component. Un Desbordamiento de Búfer en Graphviz Graph Visualization Tools desde el ID del commit f8b9e035 y versiones anteriores, permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (bloqueo de la aplicación) al cargar un archivo diseñado en el componente "lib/common/shapes.c" A flaw was found in graphviz. A wrong assumption in record_init function leads to an off-by-one write in parse_reclbl function, allowing an attacker who can provide graph input to potentially execute code when the label of a node is invalid and shorter than two characters. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://gitlab.com/graphviz/graphviz/-/issues/1700 https://lists.debian.org/debian-lts-announce/2021/05/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/D5PQPHJHPU46FK3R5XBP3XDT4X37HMPC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QGY2IGARE6RZHTF2UEZEWLMQCDILFK6A https://security.gentoo.org/glsa/202107-04 https://www.debian.org/security/2021/dsa-4914 https://access.redhat.com/security/cve/CVE-2020-18032 ht • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-193: Off-by-one Error •
CVSS: 7.5EPSS: 6%CPEs: 48EXPL: 0CVE-2021-25215 – An assertion check can fail while answering queries for DNAME records that require the DNAME to be processed to resolve itself
https://notcve.org/view.php?id=CVE-2021-25215
In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a query for a record triggering the flaw described above, the named process will terminate due to a failed assertion check. The vulnerability affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other versions of BIND 9. En BIND versiones 9.0.0 posteriores a 9.11.29, versiones 9.12.0 posteriores a 9.16.13, y BIND versiones 9.9.3-S1 posteriores a 9.11.29-S1 y versiones 9.16.8-S1 posteriores a 9.16.13-S1 de BIND Supported Preview Edition, así como versiones de lanzamiento 9.17.0 posteriores a 9.17.11 de la rama de desarrollo de BIND versión 9.17, cuando una versión vulnerable de named recibe una consulta para un registro que desencadena un fallo descrito anteriormente, el proceso named terminará debido a un comprobación de afirmación fallido. La vulnerabilidad afecta a todas las ramas de BIND 9 que se mantienen actualmente (9.11, 9.11-S, 9.16, 9.16-S, 9.17), así como a todas las demás versiones de BIND 9 A flaw was found in bind. The way DNAME records are processed may trigger the same RRset to the ANSWER section to be added more than once which causes an assertion check to fail. • http://www.openwall.com/lists/oss-security/2021/04/29/1 http://www.openwall.com/lists/oss-security/2021/04/29/2 http://www.openwall.com/lists/oss-security/2021/04/29/3 http://www.openwall.com/lists/oss-security/2021/04/29/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25215 https://lists.debian.org/debian-lts-announce/2021/05/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce& • CWE-617: Reachable Assertion •
CVSS: 6.5EPSS: 0%CPEs: 48EXPL: 0CVE-2021-25214 – A broken inbound incremental zone update (IXFR) can cause named to terminate unexpectedly
https://notcve.org/view.php?id=CVE-2021-25214
In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR triggering the flaw described above, the named process will terminate due to a failed assertion the next time the transferred secondary zone is refreshed. En BIND versiones 9.8.5 posteriores a 9.8.8, versiones 9.9.3 posteriores a 9.11.29, versiones 9.12.0 posteriores a 9.16.13, y BIND versiones 9.9.3-S1 posteriores a 9.11.29-S1 y versiones 9.16.8-S1 posteriores a 9.16.13-S1 de BIND 9 Supported Preview Edition, así como versiones de lanzamiento 9.17.0 posteriores a 9.17.11 de la rama de desarrollo de BIND versión 9.17, cuando una versión vulnerable de named recibe un IXFR malformado que desencadena el fallo descrito anteriormente, el proceso named finalizará debido a una aserción fallida la próxima vez que se actualice la zona secundaria transferida Incremental zone transfers (IXFR) provide a way of transferring changed portion(s) of a zone between servers. An IXFR stream containing SOA records with an owner name other than the transferred zone's apex may cause the receiving named server to inadvertently remove the SOA record for the zone in question from the zone database. This leads to an assertion failure when the next SOA refresh query for that zone is made. • http://www.openwall.com/lists/oss-security/2021/04/29/1 http://www.openwall.com/lists/oss-security/2021/04/29/2 http://www.openwall.com/lists/oss-security/2021/04/29/3 http://www.openwall.com/lists/oss-security/2021/04/29/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25214 https://lists.debian.org/debian-lts-announce/2021/05/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce& • CWE-617: Reachable Assertion •
