Ubuntu 18.04 LTS : OpenSSL vulnerabilities (USN-5845-1)

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5845-1 advisory. David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this issue to read arbitrary...

Important: openssl

Issue Overview: A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number o...

X.509 Name Constraints Read Buffer Overflow

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate...

Mozilla: Revocation status of S/Mime signature certificates was not checked

The Mozilla Foundation Security Advisory describes this flaw as: Certificate OCSP revocation status was not checked when verifying S/Mime signatures. Mail signed with a revoked certificate would be displayed as having a valid signature. Thunderbird versions from 68 to 102.7.0 were affected by thi...

MediaTek chip buffer error vulnerability

MediaTek chips are a variety of chips from MediaTek, a Chinese company MediaTek. A security vulnerability exists in MediaTek keyinstall, which is caused due to a lack of boundary checking and possible out-of-bounds reads...

MediaTek chip security vulnerabilities

MediaTek chips are a variety of chips from MediaTek, a Chinese company. A security vulnerability exists in the MediaTek chips, which stems from a lack of privilege checking. An attacker could exploit the vulnerability to escalate privileges...

Phar Deserialization of Untrusted Data

Description snappy is vulnerable to PHAR deserialization due to a lack of checking on the protocol before passing it into the fileexists function. If an attacker can upload files of any type to the server he can pass in the phar:// protocol to unserialize the uploaded file and instantiate arbitra...

TRENDnet TEW-820AP Stack Overflow Vulnerability

TRENDnet TEW-820AP is a router from Trendnet, Inc. A stack overflow vulnerability exists in TRENDnet TEW-820AP, which stems from a lack of length checking of the entered data in the username parameter of /formWizardPassword. An attacker could exploit this vulnerability to execute arbitrary code o...

CVE-2023-0341 Stack Buffer Overflow in editorconfig-core-c

A stack buffer overflow exists in the ecglob function of editorconfig-core-c before v0.12.6 which allowed an attacker to arbitrarily write to the stack and possibly allows remote code execution. editorconfig-core-c v0.12.6 resolved this vulnerability by bound checking all write operations over th...

Stack overflow

A CWE-120: Buffer Copy without Checking Size of Input vulnerability exists that could cause a stack-based buffer overflow, potentially leading to remote code execution when an attacker sends specially crafted time reduced data messages. Affected Products: IGSS Data Server - IGSSdataServer.exe...

Improper Input Validation

libgit2 is vulnerable to Improper Input Validation. When using an SSH remote with the optional libssh2 backend, it does not perform certificate checking by default subjecting to a man-in-the-middle attack...

CVE-2023-22742

A flaw was found in libgit2, a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Prior versions of libgit2 require the caller to set the certificatecheck field of libgit2's...

Apple macOS security vulnerabilities

Apple macOS is a specialized operating system developed by Apple Inc. for Mac computers. A security vulnerability exists in Apple macOS Ventura prior to version 13.2, which stems from a boundary-checking issue, where an application may be able to execute arbitrary code using kernel privileges...

CVE-2023-22742

CVE-2023-22742 affects libgit2 when using SSH with the optional libssh2 backend. The issue is that certificate checking is not performed by default unless a certificate_check callback is explicitly configured in git_remote_callbacks, enabling potential MITM if server SSH keys are not validated. T...
