Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Reachable Assertion (CVE-ID: CVE-2022-27939)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a reachable assertion within the get_layer4_v6() function in common/get.c in tcprewrite. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


2) Out-of-bounds read (CVE-ID: CVE-2022-27940)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to heap-based buffer over-read within he get_ipv6_next() function in common/get.c in tcprewrite. A remote attacker can perform a denial of service attack.


3) Out-of-bounds read (CVE-ID: CVE-2022-27941)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to heap-based buffer over-read within the get_l2len_protocol() function in common/get.c in tcprewrite. A remote attacker can perform a denial of service attack.


4) Out-of-bounds read (CVE-ID: CVE-2022-27942)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to heap-based buffer over-read within the parse_mpls() function in common/get.c in tcpprep. A remote attacker can perform a denial of service attack.


5) Memory leak (CVE-ID: CVE-2022-28487)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak within the fix_ipv6_checksums() function in tcpreplay. A remote attacker can force the application to leak memory and perform denial of service attack.


6) Out-of-bounds write (CVE-ID: CVE-2022-37047)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the get_ipv6_next() function in common/get.c in tcprewrite. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


7) Out-of-bounds write (CVE-ID: CVE-2022-37048)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the get_l2len_protocol() function in common/get.c in tcprewrite. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


8) Out-of-bounds write (CVE-ID: CVE-2022-37049)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the parse_mpls() function in common/get.c in tcpprep. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.
