| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2024-37371 | In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields. | [email protected] | 9.1 | 2.61% | 2024-06-28 | 2026-05-12 |
| CVE-2024-37370 | In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can modify the plaintext Extra Count field of a confidential GSS krb5 wrap token, causing the unwrapped token to appear truncated to the application. | [email protected] | 7.5 | 0.55% | 2024-06-28 | 2026-05-12 |
| CVE-2024-26462 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c. | [email protected] | 5.5 | 0.02% | 2024-02-29 | 2025-03-25 |
| CVE-2024-26461 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/lib/gssapi/krb5/k5sealv3.c. | [email protected] | 7.5 | 0.06% | 2024-02-29 | 2025-05-23 |
| CVE-2024-26458 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak in /krb5/src/lib/rpc/pmap_rmt.c. | [email protected] | 5.3 | 0.25% | 2024-02-29 | 2025-05-23 |
| CVE-2023-39975 | kdc/do_tgs_req.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one ticket to another. | [email protected] | 8.8 | 1.23% | 2023-08-16 | 2026-02-25 |
| CVE-2023-36054 | lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. | [email protected] | 6.5 | 1.10% | 2023-08-07 | 2024-11-21 |
| CVE-2022-42898 | PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug." | [email protected] | 8.8 | 10.83% | 2022-12-25 | 2025-04-14 |
| CVE-2022-39028 | telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. NOTE: MIT krb5-app | [email protected] | 7.5 | 0.40% | 2022-08-30 | 2024-11-21 |
| CVE-2020-27428 | A DOM-based cross-site scripting (XSS) vulnerability in Scratch-Svg-Renderer v0.2.0 allows attackers to execute arbitrary web scripts or HTML via a crafted sb3 file. | [email protected] | 6.1 | 0.33% | 2022-01-06 | 2024-11-21 |
| CVE-2021-37750 | The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field. | [email protected] | 6.5 | 0.72% | 2021-08-23 | 2024-11-21 |
| CVE-2021-36222 | ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash. This occurs because a return value is not properly managed in a certain situation. | [email protected] | 7.5 | 6.62% | 2021-07-22 | 2024-11-21 |
| CVE-2021-32471 | Insufficient input validation in the Marvin Minsky 1967 implementation of the Universal Turing Machine allows program users to execute arbitrary code via crafted data. For example, a tape head may have an unexpected location after the processing of input composed of As and Bs (instead of 0s and 1s). NOTE: the discoverer states "this vulnerability has no real-world implications." | [email protected] | 7.8 | 3.22% | 2021-05-10 | 2024-11-21 |
| CVE-2019-25018 | In the rcp client in MIT krb5-appl through 1.0.3, malicious servers could bypass intended access restrictions via the filename of . or an empty filename, similar to CVE-2018-20685 and CVE-2019-7282. The impact is modifying the permissions of the target directory on the client side. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8. | [email protected] | 7.5 | 0.08% | 2021-02-02 | 2024-11-21 |
| CVE-2019-25017 | An issue was discovered in rcp in MIT krb5-appl through 1.0.3. Due to the rcp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious rcp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rcp client target directory. If recursive operation (-r) is performed, the server ca | [email protected] | 5.9 | 0.52% | 2021-02-02 | 2024-11-21 |
| CVE-2020-28196 | MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit. | [email protected] | 7.5 | 0.95% | 2020-11-06 | 2025-12-03 |
| CVE-2020-7750 | This affects the package scratch-svg-renderer before 0.2.0-prerelease.20201019174008. The loadString function does not escape SVG properly, which can be used to inject arbitrary elements into the DOM via the _transformMeasurements function. | [email protected] | 9.6 | 6.18% | 2020-10-21 | 2024-11-21 |
| CVE-2020-14000 | MIT Lifelong Kindergarten Scratch scratch-vm before 0.2.0-prerelease.20200714185213 loads extension URLs from untrusted project.json files with certain _ characters, resulting in remote code execution because the URL's content is treated as a script and is executed as a worker. The responsible code is getExtensionIdForOpcode in serialization/sb3.js. The use of _ is incompatible with a protection mechanism in older versions, in which URLs were split and consequently deserialization attacks were p | [email protected] | 9.8 | 6.60% | 2020-07-16 | 2024-11-21 |
| CVE-2019-14844 | A flaw was found in, Fedora versions of krb5 from 1.16.1 to, including 1.17.x, in the way a Kerberos client could crash the KDC by sending one of the RFC 4556 "enctypes". A remote unauthenticated user could use this flaw to crash the KDC. | [email protected] | 7.5 | 11.70% | 2019-09-26 | 2024-11-21 |
| CVE-2018-20217 | A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request. | [email protected] | 5.3 | 2.67% | 2018-12-26 | 2024-11-21 |
