Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU55258
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-25704
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the Linux kernel performance monitoring subsystem when using PERF_EVENT_IOC_SET_FILTER. A local user could use this flaw to starve the resources causing denial of service.
Install updates from vendor's repository.

EUVDB-ID: #VU59473
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-36322
CWE-ID:
CWE-404 - Improper Resource Shutdown or Release
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists in the FUSE filesystem implementation in the Linux kernel due to fuse_do_getattr() calls make_bad_inode() in inappropriate situations. A local user can run a specially crafted program to trigger kernel crash.
Note, the vulnerability exists due to incomplete fix for #VU58207 (CVE-2021-28950).

CVE-ID: CVE-2021-28950
CWE-ID:
CWE-834 - Excessive Iteration
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive iteration in fs/fuse/fuse_i.h in the Linux kernel. A local user can run a specially crafted program to perform a denial of service attack.

CVE-ID: CVE-2021-42739
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary within the firewire subsystem in the Linux kernel in drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c files. A local privileged user can run a specially crafted program tat calls avc_ca_pmt() function to trigger memory corruption and execute arbitrary code with elevated privileges.
