CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 4CVE-2017-1000112 – Linux Kernel - UDP Fragmentation Offset 'UFO' Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-1000112
Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. • https://www.exploit-db.com/exploits/45147 https://www.exploit-db.com/exploits/47169 https://www.exploit-db.com/exploits/43418 https://github.com/ol0273st-s/CVE-2017-1000112-Adpated http://seclists.org/oss-sec/2017/q3/277 http://www.debian.org/security/2017/dsa-3981 http://www.securityfocus.com/bid/100262 http://www.securitytracker.com/id/1039162 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redh • CWE-122: Heap-based Buffer Overflow CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. • http://www.debian.org/security/2017/dsa-3981 http://www.securityfocus.com/bid/100267 http://www.securitytracker.com/id/1039132 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redhat.com/errata/RHSA-2017:2931 https://access.redhat.com/errata/RHSA-2017:3200 https://access.redhat.com/security/cve/cve-2017-1000111 https://access.redhat.com/security/cve/CVE-2017-1000111 https://bugzilla.redhat.com/show_bug.cgi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-787: Out-of-bounds Write •

This affects the Linux kernel 4.9-stable tree, 4.12-stable tree, 3.18-stable tree, and 4.4-stable tree.

CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 1CVE-2017-7533 – Linux Kernel < 3.16.39 (Debian 8 x64) - 'inotfiy' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-7533
Race condition in the fsnotify implementation in the Linux kernel through 4.12.4 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted application that leverages simultaneous execution of the inotify_handle_event and vfs_rename functions. Una condición de carrera en la implementación de fsnotify en el kernel de Linux hasta la versión 4.12.4, permite a los usuarios locales alcanzar privilegios o causar una denegación de servicio (corrupción de memoria) por medio de una aplicación creada que aprovecha la ejecución simultánea de las funciones inotify_handle_event y vfs_rename. A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation. • https://www.exploit-db.com/exploits/44302 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=49d31c2f389acfe83417083e1208422b4091cd9e http://openwall.com/lists/oss-security/2017/08/03/2 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-642: External Control of Critical State Data •
CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2017-7541 – kernel: Possible heap buffer overflow in brcmf_cfg80211_mgmt_tx()
https://notcve.org/view.php?id=CVE-2017-7541
The brcmf_cfg80211_mgmt_tx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux kernel before 4.12.3 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted NL80211_CMD_FRAME Netlink packet. La función brcmf_cfg80211_mgmt_tx en el archivo drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c en el kernel de Linux anterior a la versión 4.12.3, permite a los usuarios locales causar una denegación de servicio (desbordamiento de búfer y bloqueo del sistema) o posiblemente alcanzar privilegios por medio de un paquete de Netlink NL80211_CMD_FRAME creado. Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8f44c9a41386729fea410e688959ddaa9d51be7c http://openwall.com/lists/oss-security/2017/07/24/2 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.12.3 http://www.securityfocus.com/bid/99955 http://www.securitytracker.com/id/1038981 https://access.redhat.com/errata/RHSA-2017:2863 https://access.redhat.co • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
