Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2015-0207)

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:L/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 insufficient validation of user-supplied input in the dtls1_listen function in d1_lib.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) NULL pointer dereference (CVE-ID: CVE-2015-0208)

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:L/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 the ASN.1 signature-verification implementation in the rsa_item_verify function in crypto/rsa/rsa_ameth.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


3) Cryptographic issues (CVE-ID: CVE-2015-0285)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the ssl3_client_hello function in s3_clnt.c does not ensure that the PRNG is seeded before proceeding with a handshak. A remote attacker can gain unauthorized access to sensitive information on the system.


4) NULL pointer dereference (CVE-ID: CVE-2015-0290)

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:L/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 the multi-block feature in the ssl3_write_bytes function in s3_pkt.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


5) NULL pointer dereference (CVE-ID: CVE-2015-0291)

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:L/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 the sigalgs implementation in t1_lib.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
