Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2020-14556)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Libraries component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
2) Improper input validation (CVE-ID: CVE-2020-14621)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the JAXP component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
3) Improper input validation (CVE-ID: CVE-2020-14593)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the 2D component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
4) Improper input validation (CVE-ID: CVE-2020-14583)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the Java component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
5) Improper input validation (CVE-ID: CVE-2020-14579)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Libraries component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
6) Improper input validation (CVE-ID: CVE-2020-14578)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Libraries component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
7) Improper input validation (CVE-ID: CVE-2020-14577)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the JSSE component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
8) Out-of-bounds write (CVE-ID: CVE-2020-12654)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the "mwifiex_ret_wmm_get_status()" function in "drivers/net/wireless/marvell/mwifiex/wmm.c" file. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-12653)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions in the "mwifiex_cmd_append_vsie_tlv()" function in "drivers/net/wireless/marvell/mwifiex/scan.c" file. A local user can gain elevated privileges on the target system.
10) Improper Privilege Management (CVE-ID: CVE-2020-10757)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.
11) Use-after-free (CVE-ID: CVE-2019-19527)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to use-after-free error in the drivers/hid/usbhid/hiddev.c driver. A local user can use a malicious USB device to trigger use-after-free error and execute arbitrary code on the system with elevated privileges.
12) NULL pointer dereference (CVE-ID: CVE-2020-10711)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the Linux kernel's SELinux subsystem when importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated.
A remote attacker can send specially crafted packets the affected system, trigger a NULL pointer dereference error and crash the Linux kernel.
13) Use-after-free (CVE-ID: CVE-2019-19768)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the __blk_add_trace() function in kernel/trace/blktrace.c. A local user can run a specially crafted program, trigger a use-after-free error and execute arbitrary code on the system with elevated privileges.
14) Double Free (CVE-ID: CVE-2017-18595)
The vulnerability allows a local user to escalate privileges in the system.
The vulnerability exists due to a boundary error within the allocate_trace_buffer() function in the kernel/trace/trace.c. A local user can run a specially crafted application to trigger a double free error and execute arbitrary code on the target system with elevated privileges.
