Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data." } ], "affected": [ { "vendor": "n/a", "product": "GNU glibc", "versions": [ { "version": "2.30.9000", "status": "affected" } ] } ], "references": [ { "name": "FEDORA-2020-d860479b2a", "tags": [ "vendor-advisory" ], "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/URXOIA2LDUKHQXK4BE55BQBRI6ZZG3Y6/" }, { "name": "FEDORA-2020-4e92a61688", "tags": [ "vendor-advisory" ], "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SPYXTDOOB4PQGTYAMZAZNJIB3FF6YQXI/" }, { "name": "GLSA-202101-20", "tags": [ "vendor-advisory" ], "url": "https://security.gentoo.org/glsa/202101-20" }, { "name": "[mina-dev] 20210225 [jira] [Created] (FTPSERVER-500) Security vulnerability in common/lib/log4j-1.2.17.jar", "tags": [ "mailing-list" ], "url": "https://lists.apache.org/thread.html/rf9fa47ab66495c78bb4120b0754dd9531ca2ff0430f6685ac9b07772%40%3Cdev.mina.apache.org%3E" }, { "url": "https://sourceware.org/bugzilla/show_bug.cgi?id=25620" }, { "url": "https://www.talosintelligence.com/vulnerability_reports/TALOS-2020-1019" }, { "name": "[debian-lts-announce] 20221017 [SECURITY] [DLA 3152-1] glibc security update", "tags": [ "mailing-list" ], "url": "https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html" } ], "metrics": [ { "cvssV3_0": { "version": "3.0", "vectorString": "CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8.1, "baseSeverity": "HIGH" } } ], "problemTypes": [ { "descriptions": [ { "type": "CWE", "lang": "en", "description": "CWE-195: Signed to Unsigned Conversion Error", "cweId": "CWE-195" } ] } ] }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-04T08:47:40.958Z" }, "title": "CVE Program Container", "references": [ { "name": "FEDORA-2020-d860479b2a", "tags": [ "vendor-advisory", "x_transferred" ], "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/URXOIA2LDUKHQXK4BE55BQBRI6ZZG3Y6/" }, { "name": "FEDORA-2020-4e92a61688", "tags": [ "vendor-advisory", "x_transferred" ], "url": "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SPYXTDOOB4PQGTYAMZAZNJIB3FF6YQXI/" }, { "name": "GLSA-202101-20", "tags": [ "vendor-advisory", "x_transferred" ], "url": "https://security.gentoo.org/glsa/202101-20" }, { "name": "[mina-dev] 20210225 [jira] [Created] (FTPSERVER-500) Security vulnerability in common/lib/log4j-1.2.17.jar", "tags": [ "mailing-list", "x_transferred" ], "url": "https://lists.apache.org/thread.html/rf9fa47ab66495c78bb4120b0754dd9531ca2ff0430f6685ac9b07772%40%3Cdev.mina.apache.org%3E" }, { "url": "https://sourceware.org/bugzilla/show_bug.cgi?id=25620", "tags": [ "x_transferred" ] }, { "url": "https://www.talosintelligence.com/vulnerability_reports/TALOS-2020-1019", "tags": [ "x_transferred" ] }, { "name": "[debian-lts-announce] 20221017 [SECURITY] [DLA 3152-1] glibc security update", "tags": [ "mailing-list", "x_transferred" ], "url": "https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html" } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-02-13T20:06:27.632557Z", "id": "CVE-2020-6096", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-02-13T20:07:01.862Z" } } ] } }
