Analysis Summary
CVE-2018-12547
In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer. This functions were not directly callable by non-native user code.
CVE-2018-11212
An issue was discovered in libjpeg 9a. The alloc_sarray function in jmemmgr.c allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted file.
CVE-2018-12549
In Eclipse OpenJ9 version 0.11.0, the OpenJ9 JIT compiler may incorrectly omit a null check on the receiver object of an Unsafe call when accelerating it.
CVE-2019-2422
Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries). Supported versions that are affected are Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data.
CVE-2019-2449
Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Deployment). The supported version that is affected is Java SE: 8u192. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE.
