Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2021-42379)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "next_input_file" function. A remote administrator can execute arbitrary code on the target system.
2) Cross-site scripting (CVE-ID: CVE-2022-23395)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Use-after-free (CVE-ID: CVE-2021-42386)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "nvalloc" function. A remote administrator can execute arbitrary code on the target system.
4) Use-after-free (CVE-ID: CVE-2021-42385)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "evaluate" function. A remote administrator can execute arbitrary code on the target system.
5) Use-after-free (CVE-ID: CVE-2021-42384)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "handle_special" function. A remote administrator can execute arbitrary code on the target system.
6) Use-after-free (CVE-ID: CVE-2021-42383)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the awk applet. A remote privileged user can pass a specially crafted input to the application, trigger a use-after-free error and execute arbitrary code.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
7) Use-after-free (CVE-ID: CVE-2021-42382)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "getvar_s" function. A remote administrator can execute arbitrary code on the target system.
8) Use-after-free (CVE-ID: CVE-2021-42381)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "hash_init" function. A remote administrator can execute arbitrary code on the target system.
9) Use-after-free (CVE-ID: CVE-2021-42380)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "next_input_file" function. A remote administrator can execute arbitrary code on the target system.
10) Use-after-free (CVE-ID: CVE-2021-42378)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "getvar_i" function. A remote administrator can execute arbitrary code on the target system.
11) Release of invalid pointer or reference (CVE-ID: CVE-2021-42377)
The vulnerability allows a remote attacker execute arbitrary code on the system.
The vulnerability exists due to improper input validation within the hush applet. A remote attacker can pass a specially crafted input to the application and potentially execute arbitrary shell commands.
12) NULL pointer dereference (CVE-ID: CVE-2021-42376)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in Busybox's hush applet when processing a crafted shell command with a \x03 delimiter character. A local user can pass specially crafted string to the affected applet and crash the application.
13) Input validation error (CVE-ID: CVE-2021-42375)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the ash applet. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
14) Out-of-bounds read (CVE-ID: CVE-2021-42374)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in "unlzma". A remote attacker can trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
15) NULL pointer dereference (CVE-ID: CVE-2021-42373)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the man applet when a section name is supplied but no page argument is given. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
16) Buffer overflow (CVE-ID: CVE-2018-25032)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
17) Information Exposure Through an Error Message (CVE-ID: CVE-2018-12886)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c. A remote attacker can gain unauthorized access to sensitive information on the system.
