Vulnerability Details
CVEID: CVE-2018-11212
DESCRIPTION: libjpeg is vulnerable to a denial of service, caused by
divide-by-zero error in the alloc_sarray function in jmemmgr.c. By persuading a
victim to open a specially-crafted file, a remote attacker could exploit this
vulnerability to cause the application to crash.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143429 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2019-2426
DESCRIPTION: An unspecified vulnerability related to the Java SE Networking
component could allow an unauthenticated attacker to obtain sensitive
information resulting in a low confidentiality impact using unknown attack
vectors.
CVSS Base Score: 3.7
