Vulnerability Details

CVEID:CVE-2020-10735
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by the failure to limit amount of digits converting text to int by the int() type in PyLong_FromString(). A remote attacker could exploit this vulnerability to consume all available resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235840 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-2022-3627
**DESCRIPTION:**LibTIFF is vulnerable to a denial of service, caused by an out-of-bounds write flaw in the _TIFFmemcpy function in libtiff/tif_unix.c. By persuading a victim to open a specially-crafted TIFF image file, a remote 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/239184 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-3970
**DESCRIPTION:**libtiff could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in function TIFFReadRGBATileExt of the file libtiff/tif_getimage.c. By persuading a victim to open a specially-crafted TIFF file, an attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241668 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L)

CVEID:CVE-2022-35252
**DESCRIPTION:**cURL libcurl is vulnerable to a denial of service, caused by a flaw when cookies contain control codes are later sent back to an HTTP(S) server. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a “sister site” to deny service to siblings.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/234980 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-2022-36227
**DESCRIPTION:**libarchive s vulnerable to a denial of service, caused by a NULL pointer dereference flaw due to not check for an error after calling calloc 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/241187 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-2022-43552
**DESCRIPTION:**cURL libcurl is vulnerable to a denial of service, caused by a use-after-free flaw when using an HTTP proxy. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242799 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-2022-45061
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by an unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder. By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause a CPU denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240593 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-2023-0361
**DESCRIPTION:**GnuTLS could allow a remote attacker to obtain sensitive information, caused by a timing side-channel flaw in the handling of RSA ClientKeyExchange messages. By recovering the secret from the ClientKeyExchange message, an attacker could exploit this vulnerability to decrypt the application data exchanged over that connection, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/247680 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2023-2828
**DESCRIPTION:**ISC BIND is vulnerable to a denial of service, caused by a flaw that allows the named’s configured cache size limit to be significantly exceeded. By querying the resolver for specific RRsets in a certain order, a remote attacker could exploit this vulnerability to exhaust all memory on the host.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258607 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-2023-27535
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a FTP too eager connection reuse flaw. By sending a specially crafted request, an attacker could exploit this vulnerability to reuse a previously created FTP connection.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/250530 for the current score.
