CVE-2020-25647 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 7.6 High
A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25645 6 Canonical, Debian, Linux and 3 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 7.5 High
A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
CVE-2020-25643 6 Debian, Linux, Netapp and 3 more 8 Debian Linux, Linux Kernel, H410c and 5 more 2024-11-21 7.2 High
A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25641 5 Canonical, Debian, Linux and 2 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 5.5 Medium
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-25639 3 Fedoraproject, Linux, Redhat 5 Fedora, Linux Kernel, Enterprise Linux and 2 more 2024-11-21 4.4 Medium
A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system.
CVE-2020-25637 2 Opensuse, Redhat 4 Leap, Advanced Virtualization, Enterprise Linux and 1 more 2024-11-21 6.7 Medium
A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25632 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 8.2 High
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25613 3 Fedoraproject, Redhat, Ruby-lang 7 Fedora, Enterprise Linux, Rhel E4s and 4 more 2024-11-21 7.5 High
An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.
CVE-2020-25285 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 6.4 Medium
A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.
CVE-2020-25284 4 Debian, Linux, Opensuse and 1 more 4 Debian Linux, Linux Kernel, Leap and 1 more 2024-11-21 4.1 Medium
The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe.
CVE-2020-25275 4 Debian, Dovecot, Fedoraproject and 1 more 4 Debian Linux, Dovecot, Fedora and 1 more 2024-11-21 7.5 High
Dovecot before 2.3.13 has Improper Input Validation in lda, lmtp, and imap, leading to an application crash via a crafted email message with certain choices for ten thousand MIME parts.
CVE-2020-25212 5 Canonical, Debian, Linux and 2 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 7.0 High
A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.
CVE-2020-25211 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2024-11-21 6.0 Medium
In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
CVE-2020-25097 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Cloud Manager and 3 more 2024-11-21 8.6 High
An issue was discovered in Squid through 4.13 and 5.x through 5.0.4. Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings.
CVE-2020-24977 7 Debian, Fedoraproject, Netapp and 4 more 20 Debian Linux, Fedora, Active Iq Unified Manager and 17 more 2024-11-21 6.5 Medium
GNOME project libxml2 v2.9.10 has a global buffer over-read vulnerability in xmlEncodeEntitiesInternal at libxml2/entities.c. The issue has been fixed in commit 50f06b3e.
CVE-2020-24870 2 Libraw, Redhat 2 Libraw, Enterprise Linux 2024-11-21 8.8 High
Libraw before 0.20.1 has a stack buffer overflow via LibRaw::identify_process_dng_fields in identify.cpp.
CVE-2020-24659 5 Canonical, Fedoraproject, Gnu and 2 more 5 Ubuntu Linux, Fedora, Gnutls and 2 more 2024-11-21 7.5 High
An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.
CVE-2020-24606 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 8.6 High
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.
CVE-2020-24588 9 Arista, Cisco, Debian and 6 more 351 C-100, C-100 Firmware, C-110 and 348 more 2024-11-21 3.5 Low
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
CVE-2020-24587 7 Arista, Cisco, Debian and 4 more 333 C-100, C-100 Firmware, C-110 and 330 more 2024-11-21 2.6 Low
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.
