An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
A flaw was found in the way the Hotspot component of OpenJDK handled array indexes on 64-bit x86 platform. A large index could trigger a displacement overflow in LIRGenerator::emitarrayaddress, possibly leading to an access at an invalid array position.
A flaw was found in the way the Hotspot component of OpenJDK processed classes with fields that needed to be written to in Rewriter::scanmethod(). A specially-crafted Java class file could use this flaw to crash Java virtual machine.
An integer overflow flaw was found in the fix applied to the BMPImageReader class implementation in the ImageIO component of OpenJDK to address the CVE-2021-35586 (bug 2015308) issue. This issue could allow a specially-crafted BMP image to bypass previously applied protection and cause a Java application to allocate an excessive amount of memory when opened.
A flaw was found in the way the Attributes class in the Libraries component of OpenJDK performed reading of attributes with very long values from JAR file manifests. A specially-crafted JAR archive could cause a Java application reading its manifest to use excessive amount of system resources and hang.
A flaw was found in the way the BMPImageReader class implementation in the ImageIO component of OpenJDK preformed memory allocations when reading palette information from BMP images. A specially-crafted BMP file could cause a Java application to consume an excessive amount of memory when opened.
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.

An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
An unspecified vulnerability in Java SE related to the 2D component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
An unspecified vulnerability in Java SE related to the JSSE component could allow an unauthenticated attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
An unspecified vulnerability in Java SE related to the JSSE component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. The highest threat from this vulnerability is to data confidentiality.
An issue was discovered in Docker Engine before 19.03.11. An attacker in a container, with the CAPNETRAW capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain sensitive information, or cause a denial of service.
GNU cpio could allow a local authenticated attacker to gain elevated privileges on the system, caused by the failure to properly validate input files when generating TAR archives. An attacker could exploit this vulnerability to inject any tar content and compromise the system.
A heap-based buffer overflow was found in the way sudo parses command line arguments.
As per the researcher this vulnerability:
- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);
- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.
This could lead to privilege escalation.
Impact
Pulling an intentionally malformed Docker image manifest crashes the dockerd daemon.
Patches
Versions 20.10.3 and 19.03.15 contain patches that prevent the daemon from crashing.
Credits
Maintainers would like to thank Josh Larsen, Ian Coldwater, Duffie Cooley, Rory McCune for working on the vulnerability and Brad Geesaman for responsibly disclosing it to security@docker.com.
Impact
When using --userns-remap, if the root user in the remapped namespace has access to the host filesystem they can modify files under /var/lib/docker/<remapping> that cause writing files with extended privileges.
Patches
Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user.

cURL libcurl is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the tftpreceivepacket function. By sending specially-crafted request containing an OACK without the BLKSIZE option, a remote attacker could overflow a buffer and execute arbitrary code on the system.
Mozilla Firefox could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read when importing a curve25519 private key in PKCS#8format. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to obtain sensitive information.
