NONE Summary
The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 101973 published 2017-07-26 reporter Ubuntu Security Notice (C) 2017-2019 Canonical, Inc. / NASL script (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/101973 title Ubuntu 16.04 LTS : linux-aws, linux-gke vulnerabilities (USN-3364-3) NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3324-1.NASL description It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges (CVE-2017-1000364) Roee Hay discovered that the parallel port printer driver in the Linux kernel did not properly bounds check passed arguments. A local attacker with write access to the kernel command line arguments could use this to execute arbitrary code. (CVE-2017-1000363) A double free bug was discovered in the IPv4 stack of the Linux kernel. An attacker could use this to cause a denial of service (system crash).

The following security bugs were fixed : - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882). - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544). - CVE-2017-9150: The do_check function in kernel/bpf/verifier.c in the Linux kernel did not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allowed local users to obtain sensitive address information via crafted bpf system calls (bnc#1040279). - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670) The following non-security bugs were fixed : - 9p: fix a potential acl leak (4.4.68 stable queue). - acpi / APEI: Add missing synchronize_rcu() on NOTIFY_SCI removal (bsc#1031717). - acpi / scan: Drop support for force_remove (bnc#1029607). - ahci: disable correct irq for dummy ports (bsc#1040125). - alsa: hda - Fix deadlock of controller device lock at unbinding (4.4.68 stable queue). - arm: 8452/3: PJ4: make coprocessor access sequences buildable in Thumb2 mode (4.4.68 stable queue). - arm: OMAP5 / DRA7: Fix HYP mode boot for thumb2 build (4.4.68 stable queue). - asoc: rt5640: use msleep() for long delays (bsc#1031717). - asoc: sti: Fix error handling if of_clk_get() fails (bsc#1031717). - blacklist 61e8a0d5a027 powerpc/pci: Fix endian bug in fixed PHB numbering (bsc#989311) - block: get rid of blk_integrity_revalidate() (4.4.68 stable queue). - bna: avoid writing uninitialized data into hw registers (bsc#966321 FATE#320156). - bnxt_en: allocate enough space for ->ntp_fltr_bmap (bsc#1020412 FATE#321671). - bpf, arm64: fix jit branch offset related to ldimm64 (4.4.68 stable queue). - brcmfmac: Ensure pointer correctly set if skb data location changes (4.4.68 stable queue). - brcmfmac: Make skb header writable before use (4.4.68 stable queue). - brcmfmac: restore stopping netdev queue when bus clogs up (bsc#1031717). - btrfs: add a flags field to btrfs_fs_info (bsc#1012452). - btrfs: add ASSERT for block group last seen 2020-06-05 modified 2017-06-09 plugin id 100711 published 2017-06-09 reporter This script is Copyright (C) 2017-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/100711 title openSUSE Security Update : the Linux Kernel (openSUSE-2017-666)
