Description
This security bulletin contains information about 6 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2015-3194)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in crypto/rsa/rsa_ameth.c in OpenSSL. A remote attacker can trigger denial of service conditions via an RSA PSS ASN.1 signature that lacks a mask generation function parameter.
2) Information disclosure (CVE-ID: CVE-2015-3195)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists in the ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL. A remote attacker can gain unauthorized access to sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application.
3) Race condition (CVE-ID: CVE-2015-3196)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the ssl/s3_clnt.c in OpenSSL when used for a multi-threaded client. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system via a crafted ServerKeyExchange message.
4) Double free error (CVE-ID: CVE-2016-0705)
CWE-ID: CWE-415 - Double Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
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.
5) Input validation error (CVE-ID: CVE-2016-0797)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (heap memory corruption or NULL pointer dereference) or possibly have unspecified other impact via a long digit string that is mishandled by the (1) BN_dec2bn or (2) BN_hex2bn function, related to crypto/bn/bn.h and crypto/bn/bn_print.c.
6) Buffer overflow (CVE-ID: CVE-2016-0799)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to fmtstr function in crypto/bio/b_print.c in OpenSSL improperly calculates string lengths. A remote attacker can cause a denial of service (overflow and out-of-bounds read) or possibly have unspecified other impact via a long string.
