Description
This security bulletin contains information about 6 vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2015-0209)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c. A remote attacker can perform a denial of service (DoS) attack or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import.
2) Input validation error (CVE-ID: CVE-2015-0293)
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 SSLv2 implementation. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2015-0287)
CWE-ID: CWE-119 - Memory corruption
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 boundary error in the ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
4) Input validation error (CVE-ID: CVE-2015-0286)
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 the affected device does not properly perform boolean-type comparisons within the ASN1_TYPE_cmp function in crypto/asn1/a_type.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) NULL pointer dereference (CVE-ID: CVE-2015-0289)
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 PKCS#7 implementation. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
6) NULL pointer dereference (CVE-ID: CVE-2015-0288)
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 X509_to_X509_REQ function in crypto/x509/x509_req.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
