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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
