GHSA-Q76J-GCG9-VXC6 Hugo: XSS via unescaped code-fence language in default code block renderer

Hugo's default code-block renderer wrote the Markdown code-fence language / info-string into the wrapper without HTML escaping. A fence info-string containing a quote and a payload breaks out of the attribute and injects a live script element. This is not an issue if you fully trust every file...

Cross-site Scripting (XSS)

Overview Affected versions of this package are vulnerable to Cross-site Scripting XSS via the default code block rendering. An attacker can execute arbitrary JavaScript in the context of users viewing generated pages by supplying a crafted code-fence language info-string containing malicious...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel versions 2.6.39 through 5.10.16, as used in Xen. The block, net, and SCSI backends consider certain errors as ordinary bugs, which are deliberately designed to cause kernel crashes. For errors that may be influenced by guests such as memory exhaustion...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm-verity-fec: The issue of reading parity bytes that are split across blocks has been fixed. The fecDecodeBufs function assumes that the parity bytes of the first RS codeword it decodes are never split across parity blocks. This...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cifs: fixed a small mempool leak in SMB2negotiate. In some cases of failures dialect mismatches in SMB2negotiate, after the request is sent, the checks would return -EIO. Instead, it should return rc = -EIO and then jump to negex...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in ksmbd within the Linux kernel versions 5.15 through 5.19, prior to 5.19.2. There is a heap-based buffer overflow in the setntacldacl function, which is related to the use of the SMB2QUERYINFOHE function after an incorrectly formatted SMB2SETINFOHE command...
