CVE-2023-42465: make sudo less vulnerable to ROWHAMMER attacks...

The vulnerability of the mm-answer-authpassword() function in the OpenSSH cryptographic protection mechanism allows a hacker to execute the Rowhammer attack and bypass the authentication process.

The vulnerability of the mm-answer-authpassword function in the OpenSSH cryptographic protection mechanism is related to deficiencies in the authentication process. This vulnerability arises when an operation exceeds the buffer boundaries in memory, resulting in bit manipulation errors. Exploitin...

Improper Isolation or Compartmentalization

Overview Affected versions of this package are vulnerable to Improper Isolation or Compartmentalization with the memory involved in the mmanswerauthpassword function. A co-located attacker with low privileges can escalate privileges by inducing bit flips through ROWHAMMER attacks on stack variabl...

Sudo Security Breach

Sudo is a program for use on Unix-like systems that allows users to execute commands in a secure manner with special privileges. A security vulnerability exists in versions of Sudo prior to 1.9.15, which stems from vulnerability to a ROWHAMMER attack that can bypass SUDO authentication...

[slackware-security] sudo

New sudo packages are available for Slackware 14.0, 14.1, 14.2, 15.0, and -current to fix security issues. Here are the details from the Slackware 15.0 ChangeLog: patches/packages/sudo-1.9.15-i586-1slack15.0.txz: Upgraded. The sudoers plugin has been modified to make it more resilient to ROWHAMME...

F5 Networks BIG-IP : Rowhammer hardware vulnerability (K60570139)

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K60570139 advisory. - Modern DRAM chips DDR4 and LPDDR4 after 2015 are affected by a vulnerability in deployment of internal mitigations...

K60570139: Rowhammer hardware vulnerability CVE-2020-10255

Security Advisory Description Modern DRAM chips DDR4 and LPDDR4 after 2015 are affected by a vulnerability in deployment of internal mitigations against RowHammer attacks known as Target Row Refresh TRR, aka the TRRespass issue. To exploit this vulnerability, the attacker needs to create certain...

SUSE CVE-2020-10255

Modern DRAM chips DDR4 and LPDDR4 after 2015 are affected by a vulnerability in deployment of internal mitigations against RowHammer attacks known as Target Row Refresh TRR, aka the TRRespass issue. To exploit this vulnerability, the attacker needs to create certain access patterns to trigger bit...

SUSE CVE-2021-42114

Modern DRAM devices PC-DDR4, LPDDR4X are affected by a vulnerability in their internal Target Row Refresh TRR mitigation against Rowhammer attacks. Novel non-uniform Rowhammer access patterns, consisting of aggressors with different frequencies, phases, and amplitudes allow triggering bit flips o...

Information Exposure

Overview Affected versions of this package are vulnerable to Information Exposure via fault injection achieved with a rowhammer attack, which exposes ECDSA keys. Remediation Upgrade wolfssl to version 5.5.1 or higher. References - GitHub Commit - GitHub PR - GitHub Release Credit: Yarkin Doroz,...

DEBIAN-CVE-2022-42961

An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via ...
