CVE-2018-1130 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
Linux kernel before version 4.16-rc7 is vulnerable to a null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in that allows a local user to cause a denial of service by a number of certain crafted system calls.
CVE-2018-1126 5 Canonical, Debian, Procps-ng Project and 2 more 10 Ubuntu Linux, Debian Linux, Procps-ng and 7 more 2024-11-21 7.5 HIGH 4.8 MEDIUM
procps-ng before version 3.3.15 is vulnerable to an incorrect integer size in proc/alloc.* leading to truncation/integer overflow issues. This flaw is related to CVE-2018-1124.
CVE-2018-1125 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash.
CVE-2018-1124 6 Canonical, Debian, Opensuse and 3 more 9 Ubuntu Linux, Debian Linux, Leap and 6 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users.
CVE-2018-1123 3 Canonical, Debian, Procps-ng Project 3 Ubuntu Linux, Debian Linux, Procps-ng 2024-11-21 5.0 MEDIUM 3.9 LOW
procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).
CVE-2018-1122 3 Canonical, Debian, Procps-ng Project 3 Ubuntu Linux, Debian Linux, Procps-ng 2024-11-21 4.4 MEDIUM 7.3 HIGH
procps-ng before version 3.3.15 is vulnerable to a local privilege escalation in top. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function.
CVE-2018-1120 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 3.5 LOW 2.8 LOW
A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks).
CVE-2018-1118 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 2.1 LOW 2.3 LOW
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
CVE-2018-1116 3 Canonical, Debian, Polkit Project 3 Ubuntu Linux, Debian Linux, Polkit 2024-11-21 3.6 LOW 4.4 MEDIUM
A flaw was found in polkit before version 0.116. The implementation of the polkit_backend_interactive_authority_check_authorization function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.
CVE-2018-1108 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated.
CVE-2018-1106 4 Canonical, Debian, Packagekit Project and 1 more 9 Ubuntu Linux, Debian Linux, Packagekit and 6 more 2024-11-21 2.1 LOW 5.5 MEDIUM
An authentication bypass flaw has been found in PackageKit before 1.1.10 that allows users without administrator privileges to install signed packages. A local attacker can use this vulnerability to install vulnerable packages to further compromise a system.
CVE-2018-1100 3 Canonical, Redhat, Zsh 5 Ubuntu Linux, Enterprise Linux Desktop, Enterprise Linux Server and 2 more 2024-11-21 7.2 HIGH 7.8 HIGH
zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the utils.c:checkmailpath function. A local attacker could exploit this to execute arbitrary code in the context of another user.
CVE-2018-1094 3 Canonical, Linux, Redhat 5 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 2 more 2024-11-21 7.1 HIGH 5.5 MEDIUM
The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image.
CVE-2018-1087 4 Canonical, Debian, Linux and 1 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2024-11-21 4.6 MEDIUM 8.0 HIGH
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.
CVE-2018-1084 4 Canonical, Corosync, Debian and 1 more 4 Ubuntu Linux, Corosync, Debian Linux and 1 more 2024-11-21 7.5 HIGH 7.5 HIGH
corosync before version 2.4.4 is vulnerable to an integer overflow in exec/totemcrypto.c.
CVE-2018-1083 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2024-11-21 7.2 HIGH 7.8 HIGH
Zsh before version 5.4.2-test-1 is vulnerable to a buffer overflow in the shell autocomplete functionality. A local unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use autocomplete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation.
CVE-2018-1071 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2024-11-21 2.1 LOW 5.5 MEDIUM
zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the exec.c:hashcmd() function. A local attacker could exploit this to cause a denial of service.
CVE-2018-1068 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 7.2 HIGH 6.7 MEDIUM
A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.
CVE-2018-1066 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 7.1 HIGH 6.5 MEDIUM
The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response is mishandled during session recovery.
CVE-2018-1061 5 Canonical, Debian, Fedoraproject and 2 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2024-11-21 5.0 MEDIUM 6.5 MEDIUM
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in the difflib.IS_LINE_JUNK method. An attacker could use this flaw to cause denial of service.
