Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU54560
Risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-33574
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the mq_notify() function in the GNU C Library. A remote attacker can force the library to use the notification thread attributes object (passed through its struct
sigevent parameter) after it has been freed by the caller, leading to a
denial of service or possibly remote code execution.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationUpdate the affected package glibc to the latest version.

2) Integer overflow
EUVDB-ID: #VU55972
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-35942
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information or perform a DoS attack.
The vulnerability exists due to integer overflow in parse_param in posix/wordexp.c in the GNU C Library when called with an untrusted pattern. A remote attacker can pass specially crafted data to the application, trigger integer overflow and read arbitrary memory on the system of perform a denial of service (DoS) attack.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package glibc to the latest version.
