Description
This security bulletin contains information about 10 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-41741)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service attack.
The vulnerability exists due to a boundary condition within the ngx_http_mp4_module module when handling MP4 files. A remote attacker can pass a specially crafted file to the server, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
2) Out-of-bounds read (CVE-ID: CVE-2022-41742)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service attack.
The vulnerability exists due to a boundary condition within the ngx_http_mp4_module module when handling MP4 files. A remote attacker can pass a specially crafted file to the server, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-2002)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper permissions check in the Bluetooth subsystem when handling ioctl system calls of HCI sockets. A local user can acquire a trusted socket, leading to unauthorized execution of management commands.
4) Use-after-free (CVE-ID: CVE-2023-20593)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in AMD Zen2 processors. A local user can trigger a use-after-free error and execute arbitrary code on the system.
Note, the vulnerability was dubbed Zenbleed.
5) Out-of-bounds write (CVE-ID: CVE-2023-3090)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the ipvlan network driver in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
6) Use-after-free (CVE-ID: CVE-2023-3390)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within net/netfilter/nf_tables_api.c in the Linux kernel netfilter subsystem. A local user can trigger a use-after-fee error and escalate privileges on the system.
7) Out-of-bounds write (CVE-ID: CVE-2023-35001)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the nft_byteorder() function. A local user can trigger an out-of-bounds write and execute arbitrary code on the target system.
8) Out-of-bounds write (CVE-ID: CVE-2023-35788)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the fl_set_geneve_opt() function in net/sched/cls_flower.c in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
9) Use-after-free (CVE-ID: CVE-2023-3776)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the the Linux kernel's net/sched: cls_fw component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
10) Use-after-free (CVE-ID: CVE-2023-4004)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. A local user can execute arbitrary code with elevated privileges.
