{"id":"MGASA-2023-0010","summary":"Updated samba packages fix security vulnerability","details":"There is a limited write heap buffer overflow in the GSSAPI unwrap_des()\nand unwrap_des3() routines of Heimdal (included in Samba). Some SMB1 write\nrequests were not correctly range checked to ensure the client had sent\nenough data to fulfill the write, allowing server memory contents to be\nwritten into the file (or printer) instead of client supplied data. The\nclient cannot control the area of the server memory that is written to the\nfile (or printer) (CVE-2022-3437)\n\nA symlink following vulnerability was found in Samba, where a user can\ncreate a symbolic link that will make 'smbd' escape the configured share\npath. This flaw allows a remote user with access to the exported part of\nthe file system under a share via SMB1 unix extensions or NFS to create\nsymlinks to files outside the 'smbd' configured share path and gain access\nto another restricted server's filesystem. (CVE-2022-3592)\n\nActive directory elevation of privilege vulnerability (CVE-2022-37966)\n\nActive directory elevation of privilege vulnerability  (CVE-2022-37967)\n\nA flaw was found in samba. The Netlogon RPC implementations may use the\nrc4-hmac encryption algorithm, which is considered weak and should be\navoided even if the client supports more modern encryption types. This\nissue could allow an attacker who knows the plain text content\ncommunicated between the samba client and server to craft data with the\nsame MD5 calculation and replace it without being detected.\n(CVE-2022-38023)\n\nActive directory integer overflow (CVE-2022-42898)\n\nActive directory can be forced to issue weak rc4-hmac encrypted tickets\n(CVE-2022-45141)\n","modified":"2026-02-04T04:32:15.732101Z","published":"2023-01-24T07:58:24Z","related":["CVE-2022-3437","CVE-2022-3592","CVE-2022-37966","CVE-2022-37967","CVE-2022-38023","CVE-2022-42898","CVE-2022-45141"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2023-0010.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=30843"},{"type":"REPORT","url":"https://lists.suse.com/pipermail/sle-security-updates/2022-September/012209.html"},{"type":"REPORT","url":"https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/OO5PL2WBIOJ6AX5KEDZSYH6ILAFYPCOW/"},{"type":"REPORT","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/YOHL3O2H4FYUTUK2D4PURO24UAX3EBPW/"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-3437.html"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-3592.html"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-42898.html"},{"type":"REPORT","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/RWT32WRO3GIUCYYBMM7WJSBXB7UVCOAU/"},{"type":"REPORT","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/FXHIAIPMFZWDIVEPCU6MTIM33HSORPOQ/"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-38023.html"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-37966.html"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-37967.html"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2022-45141.html"},{"type":"REPORT","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/VCTYD5EQRS73QZTWPOC2ZO2FL7MMYXMS/"},{"type":"REPORT","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/G2CYDXPFBQES2Z4KLZDILGXFFQ3VIGZ4/"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.15.0.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.0.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.1.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.2.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.3.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.4.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.5.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.6.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.7.html"},{"type":"REPORT","url":"https://www.samba.org/samba/history/samba-4.16.8.html"}],"affected":[{"package":{"name":"ldb","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/ldb?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.5.2-1.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}},{"package":{"name":"samba","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/samba?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.8-1.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}},{"package":{"name":"sssd","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/sssd?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.0-1.5.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}},{"package":{"name":"talloc","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/talloc?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.4-1.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}},{"package":{"name":"tdb","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/tdb?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.7-2.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}},{"package":{"name":"tevent","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/tevent?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.12.1-1.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2023-0010.json"}}],"schema_version":"1.7.3","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
