| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2023-50784 | A buffer overflow in websockets in UnrealIRCd 6.1.0 through 6.1.3 before 6.1.4 allows an unauthenticated remote attacker to crash the server by sending an oversized packet (if a websocket port is open). Remote code execution might be possible on some uncommon, older platforms. | [email protected] | 7.5 | 1.91% | 2023-12-16 | 2026-06-17 |
| CVE-2017-13649 | UnrealIRCd 4.0.13 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command. NOTE: the vendor indicates that there is no common or recommended scenario in which a root script would execute this kill command. | [email protected] | 5.5 | 0.28% | 2017-08-23 | 2026-06-16 |
| CVE-2016-7144 | The m_authenticate function in modules/m_sasl.c in UnrealIRCd before 3.2.10.7 and 4.x before 4.0.6 allows remote attackers to spoof certificate fingerprints and consequently log in as another user via a crafted AUTHENTICATE parameter. | [email protected] | 8.1 | 1.27% | 2017-01-18 | 2026-06-16 |
| CVE-2013-7384 | UnrealIRCd 3.2.10 before 3.2.10.2 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via unspecified vectors, related to SSL. NOTE: this issue was SPLIT from CVE-2013-6413 per ADT2 due to different vulnerability types. | [email protected] | 5.0 | 2.37% | 2014-05-19 | 2026-06-16 |
| CVE-2013-6413 | Use-after-free vulnerability in UnrealIRCd 3.2.10 before 3.2.10.2 allows remote attackers to cause a denial of service (crash) via unspecified vectors. NOTE: this identifier was SPLIT per ADT2 due to different vulnerability types. CVE-2013-7384 was assigned for the NULL pointer dereference. | [email protected] | 5.0 | 2.37% | 2014-05-19 | 2026-06-16 |
| CVE-2010-2075 | UnrealIRCd 3.2.8.1, as distributed on certain mirror sites from November 2009 through June 2010, contains an externally introduced modification (Trojan Horse) in the DEBUG3_DOLOG_SYSTEM macro, which allows remote attackers to execute arbitrary commands. | [email protected] | 7.5 | 83.53% | 2010-06-15 | 2026-06-16 |
| CVE-2009-4893 | Buffer overflow in UnrealIRCd 3.2beta11 through 3.2.8, when allow::options::noident is enabled, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors. | [email protected] | 6.8 | 2.51% | 2010-06-15 | 2026-06-16 |
