A deserialization flaw in jackson-databind was found allowing code execution when given maliocusly crafted input to readValue method of ObjectMapper.

An XML deserialization vulnerability was discovered in slf4j's EventData, which accepts an XML serialized string and can lead to arbitrary code execution.

A potential integer overflow issue was found in the networking back-end of QEMU. It could occur while receiving packets, because it accepted packets with large size value. Such overflow could lead to OOB buffer access issue. A user inside guest could use this flaw to crash the QEMU process resulting in DoS.

A vulnerability was found in Undertow web server before 2.0.21. An information exposure of plain text credentials through log files because Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUESTLOGGER.undertowRequestFailed(t, exchange)

A security regression for CVE-2019-9636 was discovered in python's functions urllib.parse.urlsplit and urllib.parse.urlparse, introduced with commit d537ab0ff9767ef024f26246899728f0116b1ec3. No upstream python version is affected by this regression but the vulnerable commit may already have been included downstream as part of the original fix for CVE-2019-9636.

Affected python versions ignore the user/password part before @ in the netloc component of a URL, thus it still allows an attacker to exploit the vulnerability as in CVE-2019-9636. Those functions do not properly handle URLs encoded with Punycode/Internationalizing Domain Names in Applications (IDNA), which may result in a wrong domain name (specifically the netloc component of URL - user@domain:port) being returned by those functions. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.

A vulnerability was found in Python 2.7.x through 2.7.16 and 3.x through 3.7.2. An improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization could lead to an Information Disclosure (credentials, cookies, etc. that are cached against a given hostname) in the urllib.parse.urlsplit, urllib.parse.urlparse components. A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.

A remote stack overflow in the TIPC networking module. With FORTIFYSOURCE's stricter memcpy() bounds checking, this can be exploited to cause remote DOS via kernel panic on systems using TIPC. Prior to these bounds checks, and with a canary leak (or no CONFIGSTACKPROTECTOR), this can be exploited for RCE.

A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.

sssctlruncommand() is a wrapper for running commands via a shell, using glibc's system() function call. sssctlcacheexpire() and sssctllogsfetch() allow user provided arguments, and pass them to sssctlruncommand() sssctl is limited to root user, however, if an administrator allows unprivileged users to provide arguments to the command (e.g.: via sudo), this could be used to elevate privileges via a shell injection.

Although there are no known default configuration where this flaw could be exploited, the admin could have manually created sudo rules to let regular users use sssctl commands, or could be tricked into running a specially crafted sssctl command.

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts.

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.

A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.

A flaw was found in PostgreSQL. The chief PostgreSQL client library, libpq, does not adequately reset its internal state before each connection attempt. When one requests a connection using a "host" or "hostaddr" connection parameter provided by an untrusted party, that party can thwart three security-relevant features of the client. First, they can cause PQconnectionUsedPassword() to erroneously return true. Users of contrib module "dblink" or "postgresfdw" can leverage that to use server-side login credentials that they should not be able to use. Second, attackers can cause the PQescape() family of functions to malfunction, permitting SQL injection in "postgresfdw" and likely in other applications. Third, attackers can cause sslmode=prefer to not attempt SSL/TLS at all

A heap buffer overflow issue was found in the way Slirp networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet.

A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS OR potentially leverage it to execute arbitrary code on the host with privileges of the QEMU process.

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nwproto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.

A deserialization flaw was discovered in the jackson-databind that could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaws CVE-2017-7525 and CVE-2017-17485 by blacklisting more classes that could be used maliciously.

It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.

A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBCTUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBCTUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.

A flaw was found in the Linux kernels handling of loopback devices where it mishandles the release (lorelease function) where an attacker who has permissions to setup loopback disks.

This may allow an attacker to cause a denial of service (lockacquire use-after-free) or possibly have unspecified other impact.

A vulnerability was found in the fs/inode.c:inodeinitowner() function logic of the LInux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not.

It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.

A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
