Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Data Handling (CVE-ID: CVE-2015-8985)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers to cause a denial of service (assertion failure and application crash) via vectors related to extended regular expression processing.
2) Off-by-one (CVE-ID: CVE-2021-3999)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to an off-by-one error glibc getcwd() function. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger an off-by-one error and execute arbitrary code on the target system.
3) Buffer overflow (CVE-ID: CVE-2022-23218)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the svcunix_create() in the sunrpc module ib glibc. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Buffer overflow (CVE-ID: CVE-2022-23219)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the clnt_create() function in the sunrpc module. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
