13) Denial of service (CVE-ID: CVE-2016-9843)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in zlib due to big-endian out-of-bounds pointer. A remote attacker can send a specially crafted document, trick the victim into opening it, and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
14) Denial of service (CVE-ID: CVE-2016-9842)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in zlib due to an undefined left shift of negative number. A remote attacker can send a specially crafted document, trick the victim into opening it, and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
15) Denial of service (CVE-ID: CVE-2016-9840)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in zlib due to out-of-bounds pointer arithmetic in inftrees.c. A remote attacker can send a specially crafted document, trick the victim into opening it, and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
16) Information disclosure (CVE-ID: CVE-2016-10165)
The vulnerability allows a remote attacker to obtain potentially sensitive information.The weakness exists due to a flaw in the 2D (Little CMS 2) component. A remote attacker can read arbitrary files on the target system.
17) Weak passwords requirements (CVE-ID: CVE-2018-1447)
The vulnerability allows a local unauthenticated attacker to obtain potentially sensitive information on the target system.The weakness exists due to the GSKit CMS KDB logic fails to salt the hash function resulting in weaker than expected protection of passwords. A weak password may be recovered. A local attacker can gain access to potentially sensitive information.
18) Double free error (CVE-ID: CVE-2016-0705)
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.The weakness exists due to double-free error when parsing DSA private keys. A remote attacker can trigger memory corruption and cause the service to crash.
19) Information disclosure (CVE-ID: CVE-2017-3732)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to propagating error in the x86_64 Montgomery squaring procedure. A remote attacker with access to unpatched vulnerable system that uses a shared private key with Diffie-Hellman (DH) parameters set can gain unauthorized access to sensitive private key information.
According to vendor’s advisory, this vulnerability is unlikely to be exploited in real-world attacks, as it requires significant resources and online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients.
Vulnerability exploitation against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
20) Carry propagation issue (CVE-ID: CVE-2017-3736)
The vulnerability allows a remote attacker to decrypt data.The vulnerability exists due to carry propagating bug in the x86_64 Montgomery squaring procedure (bn_sqrx8x_internal). A remote attacker can decrypt encrypted data. The vulnerability affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen.
21) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2018-1428)
The vulnerability allows a local unauthenticated attacker to obtain potentially sensitive information on the target system.The weakness exists due to IBM GSKit uses weaker than expected cryptographic algorithms. A local attacker can gain access to potentially sensitive information.
22) Integer overflow (CVE-ID: CVE-2018-1427)
The vulnerability allows a local unauthenticated attacker to cause DoS condition on the target system.The weakness exists due to IBM GSKit contains several environment variables. A local attacker can cause the service to crash.
23) Use of cryptographically weak PRNG (CVE-ID: CVE-2018-1426)
The vulnerability allows a remote unauthenticated attacker to obtain potentially sensitive information and write arbitrary files on the target system.The weakness exists due to IBM GSKit duplicates the PRNG state across fork() system calls when multiple ICC instances are loaded which can result in duplicate Session IDs and a risk of duplicate key material. A remote attacker can gain access to potentially sensitive information and write arbitrary files.
24) Information disclosure (CVE-ID: CVE-2016-0702)
The vulnerability allows a local attacker to decrypt data passed via encrypted SSL connection.The vulnerability exists in the MOD_EXP_CTIME_COPY_FROM_PREBUF() function in crypto/bn/bn_exp.c. The application does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the same Intel Sandy Bridge CPU core as a victim and leveraging cache-bank conflicts.
The vulnerability was dubbed "CacheBleed".
25) Information disclosure (CVE-ID: CVE-2017-1681)
The vulnerability allows a local attacker to obtain potentially sensitive information.The vulnerability exists in the web interface of IBM WebSphere Application Server due to the improper handling of application requests. A local attacker can send a specially crafted request and obtain unauthorized access to read a file.
