Vulnerability Details

CVEID:   CVE-2023-4813
DESCRIPTION:   glibc is vulnerable to a denial of service, caused by a use-after-free flaw in the gaih_inet function. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/265904 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2023-29491
DESCRIPTION:   ncurses is vulnerable to a denial of service, caused by a memory corruption flaw when used by a setuid application. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253259 for the current score.

CVEID:   CVE-2023-4806
DESCRIPTION:   GNU glibc is vulnerable to a denial of service, caused by a use-after-free flaw in the getaddrinfo() function. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266465 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2023-45177
DESCRIPTION:   IBM MQ is vulnerable to a denial-of-service attack due to an error within the MQ clustering logic.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268066 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2023-4527
DESCRIPTION:   glibc is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the getaddrinfo function. By sending a DNS response over TCP larger than 2048 bytes, a remote attacker could overflow a buffer, allowing an attacker to obtain sensitive information or cause a denial of service.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266261 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H)

CVEID:   CVE-2020-8552
DESCRIPTION:   Kubernetes kube-apiserver is vulnerable to a denial of service, caused by improper input validation. By sending a specially-crafted resource request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/178254 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:   CVE-2023-38545
DESCRIPTION:   libcurl and cURL are vulnerable to a heap-based buffer overflow, caused by the improper handling of hostnames longer than 255 bytes during a slow SOCKS5 proxy handshake. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268045 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2023-38546
DESCRIPTION:   cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw in the curl_easy_duphandle function if a transfer has cookies enabled when the handle is duplicated. By sending a specially crafted request, an attacker could exploit this vulnerability to insert cookies at will into a running program.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268046 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:   CVE-2023-4911
DESCRIPTION:   glibc could allow a local authenticated attacker to gain elevated privileges on the system, caused by a buffer overflow in the dynamic loader's processing of the GLIBC_TUNABLES environment variable. By sending overly long data, an attacker could exploit this vulnerability to gain root privileges on the system.
CVSS Base score: 7.8
