A local user could use this flaw to crash the system or escalate their privileges on the system.\n\n * CVE-2020-15852: An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tss_invalidate_io_bitmap mishandling causes a loss of synchronization between the I/O bitmaps of TSS and Xen, aka CID-cadfad870154.\n\n * CVE-2020-16166: The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.\n\n * CVE-2020-29369: An issue was discovered in mm/mmap.c in the Linux kernel before 5.7.11. There is a race condition between certain expand functions (expand_downwards and expand_upwards) and page-table free operations from an munmap call, aka CID-246c320a8cfe.", "Advisory": { "From": "errata.altlinux.org", "Severity": "High", "Rights": "Copyright 2024 BaseALT Ltd.", "Issued": { "Date": "2020-08-03" }, "Updated": { "Date": "2020-08-03" }, "BDUs": [ { "ID": "BDU:2020-05547", "CVSS": "AV:L/AC:M/Au:S/C:C/I:C/A:C", "CVSS3": "AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-362, CWE-416", "Href": "https://bdu.fstec.ru/vul/2020-05547", "Impact": "High", "Public": "20200724" }, { "ID": "BDU:2021-02305", "CVSS": "AV:N/AC:M/Au:N/C:P/I:N/A:N", "CVSS3": "AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N", "CWE": "CWE-200, CWE-330", "Href": "https://bdu.fstec.ru/vul/2021-02305", "Impact": "Low", "Public": "20200729" }, { "ID": "BDU:2021-02589", "CVSS": "AV:L/AC:L/Au:S/C:C/I:C/A:C", "CVSS3": "AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-276", "Href": "https://bdu.fstec.ru/vul/2021-02589", "Impact": "High", "Public": "20200720" }, { "ID": "BDU:2021-03189", "CVSS": "AV:L/AC:L/Au:S/C:C/I:C/A:C", "CVSS3": "AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-476", "Href": "https://bdu.fstec.ru/vul/2021-03189", "Impact": "High", "Public": "20200707" } ], "CVEs": [ { "ID": "CVE-2020-14356", "CVSS": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "CVSS3": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-476", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-14356", "Impact": "High", "Public": "20200819" }, { "ID": "CVE-2020-15852", "CVSS": "AV:L/AC:L/Au:N/C:P/I:P/A:P", "CVSS3": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-276", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-15852", "Impact": "High", "Public": "20200720" }, { "ID": "CVE-2020-16166", "CVSS": "AV:N/AC:M/Au:N/C:P/I:N/A:N", "CVSS3": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N", "CWE": "CWE-330", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-16166", "Impact": "Low", "Public": "20200730" }, { "ID": "CVE-2020-29369", "CVSS": "AV:L/AC:M/Au:N/C:C/I:C/A:C", "CVSS3": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-362", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2020-29369", "Impact": "High", "Public": "20201128" } ], "AffectedCPEs": { "CPEs": [ "cpe:/o:alt:spworkstation:10", "cpe:/o:alt:spserver:10" ] } } }, "Criteria": { "Operator": "AND", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:4001", "Comment": "ALT Linux must be installed" } ], "Criterias": [ { "Operator": "OR", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:20202494001", "Comment": "kernel-headers-modules-mp is earlier than 0:5.7.12-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202494002", "Comment": "kernel-headers-mp is earlier than 0:5.7.12-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20202494003", "Comment": "kernel-image-mp is earlier than 0:5.7.12-alt1" } ] } ] } } ] }
