"Vulnerability in the Java SE, Java SE Embedded product of Oracle Java
SE (component: Security). Supported versions that are affected are
Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231.
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via Kerberos to compromise Java SE, Java SE
Embedded. Successful attacks of this vulnerability can result in
unauthorized update, insert or delete access to some of Java SE, Java
SE Embedded accessible data. Note: This vulnerability applies to Java
deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets (in Java SE 8), that load and
run untrusted code (e.g., code that comes from the internet) and rely
on the Java sandbox for security. This vulnerability can also be
exploited by using APIs in the specified Component, e.g., through a
web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7
(Integrity impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N). ( CVE-2020-2590 )

In numbers.c in libxslt 1.1.33, a type holding grouping characters of
an xsl:number instruction was too narrow and an invalid
character/length combination could be passed to
xsltNumberFormatDecimal, leading to a read of uninitialized stack
data. ( CVE-2019-13118 )

Vulnerability in the Oracle GraalVM Enterprise Edition product of
Oracle GraalVM (component: Java). The supported version that is
affected is 19.3.0.2. Difficult to exploit vulnerability allows
unauthenticated attacker with network access via multiple protocols to
compromise Oracle GraalVM Enterprise Edition. Successful attacks of
this vulnerability can result in takeover of Oracle GraalVM Enterprise
Edition. Note: GraalVM Enterprise 19.3 and above includes both Java SE
8 and Java SE 11. CVSS 3.0 Base Score 8.1 (Confidentiality, Integrity
and Availability impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). (CVE-2020-2604)

Vulnerability in the Java SE product of Oracle Java SE (component:
JavaFX). The supported version that is affected is Java SE: 8u231.
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via multiple protocols to compromise Java SE.
Successful attacks of this vulnerability can result in unauthorized
creation, deletion or modification access to critical data or all Java
SE accessible data. Note: This vulnerability applies to Java
deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets (in Java SE 8), that load and
run untrusted code (e.g., code that comes from the internet) and rely
on the Java sandbox for security. This vulnerability can also be
exploited by using APIs in the specified Component, e.g., through a
web service which supplies data to the APIs. CVSS 3.0 Base Score 5.9
(Integrity impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N). (CVE-2020-2585)

Vulnerability in the Java SE product of Oracle Java SE (component:
Libraries). Supported versions that are affected are Java SE: 7u241,
8u231, 11.0.5 and 13.0.1. Difficult to exploit vulnerability allows
unauthenticated attacker with network access via multiple protocols to
compromise Java SE. Successful attacks of this vulnerability can
result in unauthorized ability to cause a partial denial of service
(partial DOS) of Java SE. Note: This vulnerability can only be
exploited by supplying data to APIs in the specified Component without
using Untrusted Java Web Start applications or Untrusted Java applets,
such as through a web service. CVSS 3.0 Base Score 3.7 (Availability
impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
(CVE-2020-2654)

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java
SE (component: Security). Supported versions that are affected are
Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231.
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via Kerberos to compromise Java SE, Java SE
Embedded. While the vulnerability is in Java SE, Java SE Embedded,
attacks may significantly impact additional products. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all Java SE, Java SE Embedded
accessible data. Note: This vulnerability applies to Java deployments,
typically in clients running sandboxed Java Web Start applications or
sandboxed Java applets (in Java SE 8), that load and run untrusted
code (e.g., code that comes from the internet) and rely on the Java
sandbox for security. This vulnerability can also be exploited by
using APIs in the specified Component, e.g., through a web service
which supplies data to the APIs. CVSS 3.0 Base Score 6.8
(Confidentiality impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N). (CVE-2020-2601)

Vulnerability in the Java SE product of Oracle Java SE (component:
JSSE). Supported versions that are affected are Java SE: 11.0.5 and
13.0.1. Difficult to exploit vulnerability allows unauthenticated
attacker with network access via HTTPS to compromise Java SE.
Successful attacks of this vulnerability can result in unauthorized
update, insert or delete access to some of Java SE accessible data as
well as unauthorized read access to a subset of Java SE accessible
data. Note: This vulnerability applies to Java deployments, typically
in clients running sandboxed Java Web Start applications or sandboxed
Java applets (in Java SE 8), that load and run untrusted code (e.g.,
code that comes from the internet) and rely on the Java sandbox for
security. This vulnerability can also be exploited by using APIs in
the specified Component, e.g., through a web service which supplies
data to the APIs. CVSS 3.0 Base Score 4.8 (Confidentiality and
Integrity impacts). CVSS Vector:

In numbers.c in libxslt 1.1.33, an xsl:number with certain format
strings could lead to a uninitialized read in
xsltNumberFormatInsertNumbers. This could allow an attacker to discern
whether a byte on the stack contains the characters A, a, I, i, or 0,
or any other character. (CVE-2019-13117)
