Vulnerability Details

CVEID:CVE-2022-29154
**DESCRIPTION:**Rsync could allow a remote attacker to bypass security restrictions, caused by improper validation of file names. By utilize man-in-the-middle attack techniques, an attacker could exploit this vulnerability to write arbitrary files inside the directories of connecting peers.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/232637 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2022-38177
**DESCRIPTION:**ISC BIND is vulnerable to a denial of service, caused by a small memory leak in the DNSSEC verification code for the ECDSA algorithm. By spoofing the target resolver with responses that have a malformed ECDSA signature, a remote attacker could exploit this vulnerability to cause named to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236705 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-40674
**DESCRIPTION:**libexpat could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free in the doContent function in xmlparse.c. An attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236116 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-2526
**DESCRIPTION:**systemd could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free flaw due to the on_stream_io() function and dns_stream_complete() function in “resolved-dns-stream.c” not incrementing the reference counting for the DnsStream object. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235161 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
