CVE-2020-10690 – kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open
https://notcve.org/view.php?id=CVE-2020-10690
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode. Se presenta un uso de la memoria previamente liberada en kernel versiones anteriores a 5.5, debido a una condición de carrera entre la liberación de ptp_clock y cdev durante la desasignación de recursos. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10690 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4419-1 https://access.redhat.com/security/cve/CVE-2020-10690 https://bugzilla.redhat.com/show_bug.cgi?id=1817141 • CWE-416: Use After Free •

CVE-2020-12653 – kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in drivers/net/wireless/marvell/mwifiex/scan.c
https://notcve.org/view.php?id=CVE-2020-12653
An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. Se detectó un problema en el kernel de Linux versiones anteriores a 5.5.4. La función mwifiex_cmd_append_vsie_tlv() en el archivo drivers/net/wireless/marvell/mwifiex/scan.c permite a usuarios locales alcanzar privilegios o causar una denegación de servicio debido a una memcpy incorrecta y al desbordamiento del búfer, también se conoce como CID-b70261a288ea. A flaw was found in the way the mwifiex_cmd_append_vsie_tlv() in Linux kernel's Marvell WiFi-Ex driver handled vendor specific information elements. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://www.openwall.com/lists/oss-security/2020/05/08/2 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b70261a288ea4d2f4ac7cd04be08a9f0f2de4f4d https://github.com/torvalds/linux/commit/b70261a288ea4d2f4ac7cd04be08a9f0f2de4f4d https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVE-2020-11652 – SaltStack Salt Path Traversal Vulnerability

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users. Se descubrió un problema en SaltStack Salt versiones anteriores a la versión 2019.2.4 y versiones 3000 anteriores a 3000.2. La clase ClearFuncs del proceso Salt-master permite acceder a algunos métodos que sanean inapropiadamente las rutas. • https://www.exploit-db.com/exploits/48421 https://github.com/ssrsec/CVE-2020-11651-CVE-2020-11652-EXP https://github.com/Al1ex/CVE-2020-11652 https://github.com/limon768/CVE-2020-11652-POC https://github.com/fanjq99/CVE-2020-11652 https://github.com/appcheck-ng/salt-rce-scanner-CVE-2020-11651-CVE-2020-11652 http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00070.html http://packetstormsecurit • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2020-11651 – SaltStack Salt Authentication Bypass Vulnerability

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.
