Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU17762
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2019-3459
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due heap address infoleak in use of l2cap_get_conf_opt. A local attacker can trigger memory leak and access important data.
MitigationUpdate the affected packages.

CVE-ID: CVE-2019-3460
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due heap address infoleak in multiple locations including function l2cap_parse_conf_rsp. A local attacker can trigger memory leak and access important data.
MitigationUpdate the affected packages.

EUVDB-ID: #VU17367
Risk: Low
CVSSv4.0: 5.5 [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:P/U:Clear]
CVE-ID: CVE-2019-7308
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to out-of-bounds speculation on pointer arithmetic in various cases in kernel/bpf/verifier.c, including cases of different branches with different state or limits to sanitize. A remote attacker can gain unauthorized access to sensitive information on the system.
MitigationUpdate the affected packages.
