Vulnerability Details
CVEID: CVE-2017-3731
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read
when using a specific cipher. By sending specially crafted truncated packets,
a remote attacker could exploit this vulnerability using CHACHA20/POLY1305 to
cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/121312
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2017-3732
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a propagation error in the BN_mod_exp() function. An attacker could
exploit this vulnerability to obtain information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/121313
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-7055
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an error in a
Broadwell-specific Montgomery multiplication procedure. By sending specially
crafted data, a remote attacker could exploit this vulnerability to trigger
errors in public-key operations in configurations where multiple remote
clients select an affected EC algorithm and cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/118748
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-9840
DESCRIPTION:
zlib is vulnerable to a denial of service, caused by an out-of-bounds pointer
arithmetic in inftrees.c. By persuading a victim to open a specially crafted
document, a remote attacker could exploit this vulnerability to cause a
denial of service.
CVSS Base Score: 3.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/120508
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-2016-9841
DESCRIPTION:
zlib is vulnerable to a denial of service, caused by an out-of-bounds pointer
arithmetic in inftrees.c. By persuading a victim to open a specially crafted
document, a remote attacker could exploit this vulnerability to cause a
denial of service.
CVSS Base Score: 3.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/120509
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-2016-9842
DESCRIPTION:
zlib is vulnerable to a denial of service, caused by an undefined left shift
of negative number. By persuading a victim to open a specially crafted
document, a remote attacker could exploit this vulnerability to cause a
denial of service.
CVSS Base Score: 3.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/120510
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-2016-9843
DESCRIPTION:
zlib is vulnerable to a denial of service, caused by a big-endian out-of-
bounds pointer. By persuading a victim to open a specially crafted document,
a remote attacker could exploit this vulnerability to cause a denial of
service.
CVSS Base Score: 3.3
