CVE-2015-1350 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Enterprise Mrg 2021-07-15 2.1 LOW 5.5 MEDIUM
The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.
CVE-2019-11478 5 Canonical, F5, Linux and 2 more 24 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 21 more 2021-07-15 5.0 MEDIUM 7.5 HIGH
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit f070ef2ac66716357066b683fb0baf55f8191a2e.
CVE-2020-1749 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Enterprise Mrg 2021-07-15 5.0 MEDIUM 7.5 HIGH
A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
CVE-2015-7837 1 Redhat 6 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server Aus and 3 more 2021-07-15 2.1 LOW 5.5 MEDIUM
The Linux kernel, as used in Red Hat Enterprise Linux 7, kernel-rt, and Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended securelevel/secureboot restrictions by leveraging improper handling of secure_boot flag across kexec reboot.
CVE-2014-3917 3 Linux, Redhat, Suse 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2021-07-15 3.3 LOW N/A
kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number.
CVE-2018-17189 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2021-07-06 5.0 MEDIUM 5.3 MEDIUM
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.
CVE-2021-20254 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2021-06-24 4.9 MEDIUM 6.8 MEDIUM
A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2019-18805 5 Broadcom, Linux, Netapp and 2 more 22 Fabric Operating System, Linux Kernel, Active Iq Unified Manager and 19 more 2021-06-22 7.5 HIGH 9.8 CRITICAL
An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.
CVE-2021-3504 3 Debian, Fedoraproject, Redhat 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2021-06-21 5.8 MEDIUM 5.4 MEDIUM
A flaw was found in the hivex library in versions before 1.3.20. It is caused due to a lack of bounds check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive) file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The highest threat from this vulnerability is to system availability.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 16 Ubuntu Linux, Debian Linux, Libcurl and 13 more 2021-06-15 7.5 HIGH 9.8 CRITICAL
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-19066 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2021-06-14 4.7 MEDIUM 4.7 MEDIUM
A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures, aka CID-0e62395da2bd.
CVE-2018-1000180 5 Bouncycastle, Debian, Netapp and 2 more 21 Fips Java Api, Legion-of-the-bouncy-castle-java-crytography-api, Debian Linux and 18 more 2021-06-14 5.0 MEDIUM 7.5 HIGH
Bouncy Castle BC 1.54 - 1.59, BC-FJA 1.0.0, BC-FJA 1.0.1 and earlier have a flaw in the Low-level interface to RSA key pair generator, specifically RSA Key Pairs generated in low-level API with added certainty may have less M-R tests than expected. This appears to be fixed in versions BC 1.60 beta 4 and later, BC-FJA 1.0.2 and later.
CVE-2020-1702 2 Containers-image Project, Redhat 2 Containers-image, Enterprise Linux 2021-06-10 4.3 MEDIUM 3.3 LOW
A malicious container image can consume an unbounded amount of memory when being pulled to a container runtime host, such as Red Hat Enterprise Linux using podman, or OpenShift Container Platform. An attacker can use this flaw to trick a user, with privileges to pull container images, into crashing the process responsible for pulling the image. This flaw affects containers-image versions before 5.2.0.
CVE-2018-11053 4 Citrix, Dell, Redhat and 1 more 4 Xenserver, Emc Idrac Service Module, Enterprise Linux and 1 more 2021-06-10 4.0 MEDIUM 6.5 MEDIUM
Dell EMC iDRAC Service Module for all supported Linux and XenServer versions v3.0.1, v3.0.2, v3.1.0, v3.2.0, when started, changes the default file permission of the hosts file of the host operating system (/etc/hosts) to world writable. A malicious low privileged operating system user or process could modify the host file and potentially redirect traffic from the intended destination to sites hosting malicious or unwanted content.
CVE-2018-3665 6 Canonical, Citrix, Debian and 3 more 14 Ubuntu Linux, Xenserver, Debian Linux and 11 more 2021-06-09 4.7 MEDIUM 5.6 MEDIUM
System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel.
CVE-2021-20229 3 Fedoraproject, Postgresql, Redhat 4 Fedora, Postgresql, Enterprise Linux and 1 more 2021-06-09 4.0 MEDIUM 4.3 MEDIUM
A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table. The highest threat from this vulnerability is to confidentiality.
CVE-2021-30469 3 Fedoraproject, Podofo Project, Redhat 3 Fedora, Podofo, Enterprise Linux 2021-06-08 4.3 MEDIUM 5.5 MEDIUM
