#vulnerability

CISA adds a critical HPE OneView flaw (CVE-2025-37164) to its KEV catalogue with a Jan 28 deadline. Learn how this 10.0 RCE bug puts server infrastructure at risk.

### Summary A denial-of-service vulnerability exists in the SM2 PKE decryption path where an invalid elliptic-curve point (C1) is decoded and the resulting value is unwrapped without checking. Specifically, `AffinePoint::from_encoded_point(&encoded_c1)` may return a `None`/`CtOption::None` when the supplied coordinates are syntactically valid but do not lie on the SM2 curve. The calling code previously used `.unwrap()`, causing a panic when presented with such input. ### Affected Component / Versions - File: `src/pke/decrypting.rs` - Function: internal `decrypt()` (invoked by `DecryptingKey::decrypt*` methods) - Affected releases: - sm2 0.14.0-rc.0 (https://crates.io/crates/sm2/0.14.0-rc.0) - sm2 0.14.0-pre.0 (https://crates.io/crates/sm2/0.14.0-pre.0) ### Details The library decodes the C1 field (an EC point) as an `EncodedPoint` and then converts it to an `AffinePoint` using `AffinePoint::from_encoded_point(&encoded_c1)`. That conversion returns a `CtOption<Affin...

### Summary A critical vulnerability exists in the SM2 Public Key Encryption (PKE) implementation where the ephemeral nonce `k` is generated with severely reduced entropy. A unit mismatch error causes the nonce generation function to request only 32 bits of randomness instead of the expected 256 bits. This reduces the security of the encryption from a 128-bit level to a trivial 16-bit level, allowing a practical attack to recover the nonce `k` and decrypt any ciphertext **given only the public key and ciphertext**. ### Affected Versions - sm2 0.14.0-rc.0 (https://crates.io/crates/sm2/0.14.0-rc.0) - sm2 0.14.0-pre.0 (https://crates.io/crates/sm2/0.14.0-pre.0) This vulnerability is introduced in commit: [Commit 4781762](https://github.com/RustCrypto/elliptic-curves/commit/4781762f23ff22ab34763410f648128055c93731) on Sep 6, 2024, which is over a year ago. ### Details The root cause of this vulnerability is a unit mismatch in the `encrypt` function located in `sm2/src/pke/encrypt...

# Fickling's assessment `cProfile` was added to the list of unsafe imports (https://github.com/trailofbits/fickling/commit/dc8ae12966edee27a78fe05c5745171a2b138d43). # Original report ## Description ### Summary Fickling versions up to and including 0.1.6 do not treat Python's `cProfile` module as unsafe. Because of this, a malicious pickle that uses `cProfile.run()` is classified as SUSPICIOUS instead of OVERTLY_MALICIOUS. If a user relies on Fickling's output to decide whether a pickle is safe to deserialize, this misclassification can lead them to execute attacker-controlled code on their system. This affects any workflow or product that uses Fickling as a security gate for pickle deserialization. ### Details The `cProfile` module is missing from fickling's block list of unsafe module imports in `fickling/analysis.py`. This is the same root cause as CVE-2025-67748 (pty) and CVE-2025-67747 (marshal/types). Incriminated source code: - File: `fickling/analysis.py` - Class: `U...

Large businesses or governments aren’t the only ones threatened by cyber attacks. Every organization is now equally threatened.…

A cross-site scripting (XSS) vulnerabilities was identified in October CMS backend configuration forms: - **Branding and Appearances Styles** A user with the `Customize Backend Styles` permission could inject malicious HTML/JS into the stylesheet input at *Settings → Branding & Appearance → Styles*. A specially crafted input could break out of the intended `<style>` context, allowing arbitrary script execution across backend pages for all users. --- ### Impact - Persistent XSS across the backend interface. - Exploitable by lower-privileged accounts with the above permissions. - Potential consequences include privilege escalation, session hijacking, and execution of unauthorized actions in victim sessions. --- ### Patches The vulnerability has been patched in **v4.0.12** and **v3.7.13**. Stylesheet inputs are now sanitized to prevent injection of arbitrary HTML/JS. All users are strongly encouraged to upgrade to the latest patched version. --- ### Workaround...

The function `mnl::cb_run` is marked as safe but exhibits unsound behavior when processing malformed Netlink message buffers. Passing a crafted byte slice to `mnl::cb_run` can trigger memory violations. The function does not sufficiently validate the input buffer structure before processing, leading to out-of-bounds reads. This vulnerability allows an attacker to cause a Denial of Service (segmentation fault) or potentially read unmapped memory by providing a malformed Netlink message.

### Impact An attacker who exploits this vulnerability can craft a PDF which leads to possibly long runtimes for invalid `startxref` entries. When rebuilding the cross-reference table, PDF files with lots of whitespace characters become problematic. Only the non-strict reading mode is affected. ### Patches This has been fixed in [pypdf==6.6.0](https://github.com/py-pdf/pypdf/releases/tag/6.6.0). ### Workarounds ```python from pypdf import PdfReader, PdfWriter # Instead of reader = PdfReader("file.pdf") # use the strict mode: reader = PdfReader("file.pdf", strict=True) # Instead of writer = PdfWriter(clone_from="file.pdf") # use an explicit strict reader: writer = PdfWriter(clone_from=PdfReader("file.pdf", strict=True)) ``` ### Resources This issue has been fixed in #3594.
