libxslt: read of uninitialized stack data due to too narrow xsl:number instruction and an invalid character

In numbers.c in libxslt 1.1.33, a type holding grouping characters of an xsl:number instruction was too narrow and an invalid character/length combination could be passed to xsltNumberFormatDecimal, leading to a read of uninitialized stack data.

libxslt: an xsl number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers

In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character.

hw: TSX Transaction Asynchronous Abort (TAA)

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

hardware: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)

Microarchitectural Data Sampling Uncacheable Memory (MDSUM): Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

libxslt: xsltCheckRead and xsltCheckWrite routines security bypass by crafted URL

libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.

openssh: Improper write operations in readonly mode allow for zero-length file creation

The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.

Untrusted search path vulnerability in the Microsoft Foundation Class (MFC) Library in Microsoft Visual Studio .NET 2003 SP1; Visual Studio 2005 SP1, 2008 SP1, and 2010; Visual C++ 2005 SP1, 2008 SP1, and 2010; and Exchange Server 2010 Service Pack 3, 2013, and 2013 allows local users to gain privileges via a Trojan horse dwmapi.dll file in the current working directory during execution of an MFC application such as AtlTraceTool8.exe (aka ATL MFC Trace Tool), as demonstrated by a directory that contains a TRC, cur, rs, rct, or res file, aka "MFC Insecure Library Loading Vulnerability."

The default configuration of Sun Java System Application Server 7 and 7 2004Q2 enables the HTTP TRACE method, which makes it easier for remote attackers to steal cookies and authentication credentials via a cross-site tracing (XST) attack, a related issue to CVE-2004-2763 and CVE-2005-3398.

OpenSSH: Plaintext Recovery Attack against CBC ciphers

Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors.

MD5: MD5 Message-Digest Algorithm is not collision resistant

The MD5 Message-Digest Algorithm is not collision resistant, which makes it easier for context-dependent attackers to conduct spoofing attacks, as demonstrated by attacks on the use of MD5 in the signature algorithm of an X.509 certificate.

The default configuration of BEA WebLogic Server and Express 8.1 SP2 and earlier, 7.0 SP4 and earlier, 6.1 through SP6, and 5.1 through SP13 responds to the HTTP TRACE request, which can allow remote attackers to steal information using cross-site tracing (XST) attacks in applications that are vulnerable to cross-site scripting.

The undocumented TRACK method in Microsoft Internet Information Services (IIS) 5.0 returns the content of the original request in the body of the response, which makes it easier for remote attackers to steal cookies and authentication credentials, or bypass the HttpOnly protection mechanism, by using TRACK to read the contents of the HTTP headers that are returned in the response, a technique that is similar to cross-site tracing (XST) using HTTP TRACE.

Adobe Acrobat Reader Untrusted Search Path Application denial-of-service

Adobe Acrobat Reader versions 23.003.20244 (and earlier) and 20.005.30467 (and earlier) are affected by an Untrusted Search Path vulnerability that could lead to Application denial-of-service. An attacker could leverage this vulnerability if the default PowerShell Set-ExecutionPolicy is set to Unrestricted, making the attack complexity high. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Vowpal Wabbit: Shell injection via crafted PR title in python_checks.yml allows arbitrary command execution on CI runner

Vowpal Wabbit is a machine learning system. The workflow .github/workflows/python_checks.yml embeds ${{ github.event.pull_request.title }} directly inside double-quoted bash strings in four separate steps across four jobs, each passing it as a CLI argument to the Python test script run_tests_model_gen_and_load.py. The shell interprets the expanded string before invoking Python, allowing an attacker to break out of the quotes and execute arbitrary commands on the runner. The pull_request trigger fires on PRs targeting any branch (branches: ['*']), with no additional access gate. This vulnerability is fixed by the 998e390e80a7e8192d7849b7784bc113dbd190ad commit.
