The parser tries to locate a log message delimiter (in this case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. The following step in the parser is to shift left the contents of the message. To do this, it will call memmove with the right pointers to the target and destination strings, but the lenMsg will now be interpreted as a huge value, causing a heap overflow.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "CentOS-8.4:rsyslog-0:8.1911.0-7.el8_4.2.tuxcare.els1.x86_64" ], "known_affected": [ "CentOS-8.4:rsyslog-0:8.1911.0-7.el8_4.2.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2019-17041" }, { "category": "external", "summary": "http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00031.html", "url": "http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00031.html" }, { "category": "external", "summary": "http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00032.html", "url": "http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00032.html" }, { "category": "external", "summary": "https://github.com/rsyslog/rsyslog/blob/v8-stable/ChangeLog", "url": "https://github.com/rsyslog/rsyslog/blob/v8-stable/ChangeLog" }, { "category": "external", "summary": "https://github.com/rsyslog/rsyslog/pull/3884", "url": "https://github.com/rsyslog/rsyslog/pull/3884" }, { "category": "external", "summary": "https://lists.debian.org/debian-lts-announce/2021/11/msg00030.html", "url": "https://lists.debian.org/debian-lts-announce/2021/11/msg00030.html" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPNCHI7X2IEXRH6RYD6IDPR4PLB5RPC7/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPNCHI7X2IEXRH6RYD6IDPR4PLB5RPC7/" }, { "category": "external", "summary": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W6SUQE25RD37CD24BHKUWMG27U5RQ2FU/", "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W6SUQE25RD37CD24BHKUWMG27U5RQ2FU/" } ], "release_date": "2019-10-07T16:15:00Z", "remediations": [ { "category": "none_available", "details": "Affected", "product_ids": [ "CentOS-8.4:rsyslog-0:8.1911.0-7.el8_4.2.x86_64" ] } ], "scores": [ { "cvss_v2": { "accessComplexity": "LOW", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "PARTIAL", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0" }, "cvss_v3": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 9.8, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1" }, "products": [ "CentOS-8.4:rsyslog-0:8.1911.0-7.el8_4.2.tuxcare.els1.x86_64", "CentOS-8.4:rsyslog-0:8.1911.0-7.el8_4.2.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Critical" } ] } ] }
