Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Resource management error
EUVDB-ID: #VU70417
Risk: Medium
CVSSv4.0: 2.7 [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]
CVE-ID: CVE-2015-1788
CWE-ID:
CWE-399 - Resource Management Errors

4) Resource management error
EUVDB-ID: #VU77185
Risk: Medium
CVSSv4.0: 2.7 [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]
CVE-ID: CVE-2015-1792
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the do_free_upto function in crypto/cms/cms_smime.c in OpenSSL. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack via vectors that trigger a NULL value of a BIO data structure.

5) Race condition
EUVDB-ID: #VU77184
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2015-1791
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL. A local user can exploit the race and cause a denial of service (double free and application crash) or possibly have unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been obtained earlier.
MitigationUpdate the affected package openssl.
