CVE-2020-22916

  • Vulnerable module: xz-utils/liblzma5
  • Introduced through: xz-utils/liblzma5@5.2.4-1ubuntu1.1

Detailed paths

  • Introduced through: buildpack-deps@focal-curl › xz-utils/liblzma5@5.2.4-1ubuntu1.1

NVD Description

Note: Versions mentioned in the description apply only to the upstream xz-utils package and not the xz-utils package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of "endless output" and "denial of service" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.

Remediation

There is no fixed version for Ubuntu:20.04 xz-utils.

Information Exposure

  • Vulnerable module: gnutls28/libgnutls30
  • Introduced through: gnutls28/libgnutls30@3.6.13-2ubuntu1.10
  • Fixed in: 3.6.13-2ubuntu1.11

Detailed paths

NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls28 package and not the gnutls28 package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.

Remediation

Upgrade Ubuntu:20.04 gnutls28 to version 3.6.13-2ubuntu1.11 or higher.

CVE-2023-26604

  • Vulnerable module: systemd/libsystemd0
  • Introduced through: systemd/libsystemd0@245.4-4ubuntu3.23 and systemd/libudev1@245.4-4ubuntu3.23

Detailed paths

  • Introduced through: buildpack-deps@focal-curl › systemd/libsystemd0@245.4-4ubuntu3.23
  • Introduced through: buildpack-deps@focal-curl › systemd/libudev1@245.4-4ubuntu3.23

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.

Remediation

There is no fixed version for Ubuntu:20.04 systemd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data.

Remediation

There is no fixed version for Ubuntu:20.04 krb5.

NVD Description

Note: Versions mentioned in the description apply only to the upstream shadow package and not the shadow package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

In Shadow 4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that "cat /etc/passwd" shows a rogue user account.
