Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-27292)
The vulnerability allows a remote attacker to perform a regular expression denial of service (ReDoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing a malicious User-Agent header. A remote attacker can trigger resource exhaustion and perform a regular expression denial of service (ReDoS) attack.
2) Use-after-free (CVE-ID: CVE-2021-3516)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in xmllint. A remote attacker can use a specially crafted file to execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
3) Out-of-bounds write (CVE-ID: CVE-2021-3517)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the xml entity encoding functionality. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
4) Use-after-free (CVE-ID: CVE-2021-3518)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in libxml2. A remote attacker can use a specially crafted file and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
5) Integer overflow (CVE-ID: CVE-2021-3520)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the fast LZ compression algorithm library. A remote attacker can pass specially crafted archive, trick the victim into opening it, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) NULL pointer dereference (CVE-ID: CVE-2021-3537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2021-3541)
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. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) Insufficient verification of data authenticity (CVE-ID: CVE-2021-20271)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an error in RPM's signature check functionality when reading package files. A remote attacker can create a specially crafted package with a modified signature header, trick the victim into installing and compromise the affected system.
9) Uncontrolled Memory Allocation (CVE-ID: CVE-2021-33910)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to stack exhaustion within the basic/unit-name.c in systemd. A local user can crash the systemd (PID 1) and cause a kernel panic.
