Vulnerability Details
CVEID: CVE-2020-22916
DESCRIPTION: XZ is vulnerable to a denial of service, caused by a flaw in the decompression algorithm when processing archive files. By persuading a victim to decompress a specially crafted file, a remote attacker could exploit this vulnerability to conduct a decompression bomb attack, resulting a denial of service.
Note: the vendor disputes this vulnerability, as the decompression of 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266535 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-48554
DESCRIPTION: File is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the file_copystr function in funcs.c. By persuading a victim to open a specially crafted file, a remote attacker could overflow a buffer and execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/264341 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2023-39128
DESCRIPTION: GNU gdb is vulnerable to a denial of service, caused by a stack-based buffer overflow in the ada_decode function in /gdb/ada-lang.c. By persuading a victim to open a specially crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261648 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-2023-39130
DESCRIPTION: GNU gdb is vulnerable to a denial of service, caused by a heap-based buffer overflow in the pe_as16 function in /gdb/coff-pe-read.c. By persuading a victim to open a specially crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/261650 for the current score.

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.
