CVE-2020-11042 3 Canonical, Debian, Freerdp 3 Ubuntu Linux, Debian Linux, Freerdp 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info. It allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has been patched in 2.0.0.
CVE-2020-11008 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 5.0 MEDIUM 4.0 MEDIUM
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker cannot control which one). Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. Many helpers will interpret this as matching _any_ URL, and will return some unspecified stored password, leaking the password to an attacker's server. The vulnerability can be triggered by feeding a malicious URL to `git clone`. However, the affected URLs look rather suspicious; the likely vector would be through systems which automatically clone URLs not visible to the user, such as Git submodules, or package systems built around Git. The root of the problem is in Git itself, which should not be feeding blank input to helpers. However, the ability to exploit the vulnerability in practice depends on which helpers are in use. Credential helpers which are known to trigger the vulnerability: - Git's "store" helper - Git's "cache" helper - the "osxkeychain" helper that ships in Git's "contrib" directory Credential helpers which are known to be safe even with vulnerable versions of Git: - Git Credential Manager for Windows Any helper not in this list should be assumed to trigger the vulnerability.
CVE-2020-10994 3 Canonical, Fedoraproject, Python 3 Ubuntu Linux, Fedora, Pillow 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
In libImaging/Jpeg2KDecode.c in Pillow before 7.1.0, there are multiple out-of-bounds reads via a crafted JP2 file.

An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.
CVE-2020-10760 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration. A Samba LDAP user could use this flaw to crash samba.
CVE-2020-10757 7 Canonical, Debian, Fedoraproject and 4 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.
CVE-2020-10756 5 Canonical, Debian, Libslirp Project and 2 more 6 Ubuntu Linux, Debian Linux, Libslirp and 3 more 2024-11-21 2.1 LOW 6.5 MEDIUM
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1.
CVE-2020-10755 2 Canonical, Redhat 2 Ubuntu Linux, Openstack-cinder 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An insecure-credentials flaw was found in all openstack-cinder versions before openstack-cinder 14.1.0, all openstack-cinder 15.x.x versions before openstack-cinder 15.2.0 and all openstack-cinder 16.x.x versions before openstack-cinder 16.1.0. When using openstack-cinder with the Dell EMC ScaleIO or VxFlex OS backend storage driver, credentials for the entire backend are exposed in the ``connection_info`` element in all Block Storage v3 Attachments API calls containing that element. This flaw enables an end-user to create a volume, make an API call to show the attachment detail information, and retrieve a username and password that may be used to connect to another user's volume. Additionally, these credentials are valid for the ScaleIO or VxFlex OS Management API, should an attacker discover the Management API endpoint. Source: OpenStack project
CVE-2020-10753 5 Canonical, Fedoraproject, Linuxfoundation and 2 more 6 Ubuntu Linux, Fedora, Ceph and 3 more 2024-11-21 4.3 MEDIUM 5.4 MEDIUM
A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. Ceph versions 3.x and 4.x are vulnerable to this issue.
CVE-2020-10732 4 Canonical, Linux, Netapp and 1 more 31 Ubuntu Linux, Linux Kernel, Active Iq Unified Manager and 28 more 2024-11-21 3.6 LOW 3.3 LOW
A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.
CVE-2020-10724 3 Canonical, Dpdk, Fedoraproject 3 Ubuntu Linux, Data Plane Development Kit, Fedora 2024-11-21 2.1 LOW 5.1 MEDIUM
A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.
CVE-2020-10723 5 Canonical, Dpdk, Fedoraproject and 2 more 6 Ubuntu Linux, Data Plane Development Kit, Fedora and 3 more 2024-11-21 4.6 MEDIUM 5.1 MEDIUM
A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption.
CVE-2020-10722 5 Canonical, Dpdk, Fedoraproject and 2 more 6 Ubuntu Linux, Data Plane Development Kit, Fedora and 3 more 2024-11-21 4.6 MEDIUM 5.1 MEDIUM
A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.
CVE-2020-10711 5 Canonical, Debian, Linux and 2 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
CVE-2020-10690 6 Canonical, Debian, Linux and 3 more 33 Ubuntu Linux, Debian Linux, Linux Kernel and 30 more 2024-11-21 4.4 MEDIUM 6.5 MEDIUM
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.
CVE-2020-10683 5 Canonical, Dom4j Project, Netapp and 2 more 38 Ubuntu Linux, Dom4j, Oncommand Api Services and 35 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
dom4j before 2.0.3 and 2.1.x before 2.1.3 allows external DTDs and External Entities by default, which might enable XXE attacks. However, there is popular external documentation from OWASP showing how to enable the safe, non-default behavior in any application that uses dom4j.
