Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory leak
EUVDB-ID: #VU29105
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-12049
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform DoS attack on the target system.
The vulnerability exists due memory leak in libdbus when a message exceeds the per-message file descriptor limit. A local user with access to the D-Bus system bus or another system service's private AF_UNIX socket can make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients.
MitigationUpdate the affected package dbus-1 to the latest version.

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Use-after-free
EUVDB-ID: #VU62883
Risk: Low
CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-35512
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error if two usernames have the same numeric UID. When a set of policy rules references these usernames, D-Bus may free some memory in the heap, which is still used by data structures necessary for the other usernames sharing the UID, which can result in crash.
MitigationUpdate the affected package dbus-1 to the latest version.
