It was discovered that the SBOM files generated by melange in apks had file system permissions mode 666: ``` $ apkrane ls https://packages.wolfi.dev/os/x86_64/APKINDEX.tar.gz -P hello-wolfi --full --latest | xargs wget -q -O - | tar tzv 2>/dev/null var/lib/db/sbom drwxr-xr-x root/root 0 2025-06-23 14:17 var/lib/db/sbom -rw-rw-rw- root/root 3383 2025-06-23 14:17 var/lib/db/sbom/hello-wolfi-2.12.2-r1.spdx.json ``` This issue was introduced in commit 1b272db ("Persist workspace filesystem throughout package builds (#1836)") ([v0.23.0](https://github.com/chainguard-dev/melange/releases/tag/v0.23.0)). ### Impact This potentially allows an unprivileged user to tamper with apk SBOMs on a running image, potentially confusing security scanners. An attacker could also perform a DoS under special circumstances. ### Patches This issue was addressed in melange in e29494b ("fix: tighten up permissions for written SBOM files and signature tarballs (#2086)") ([v0.29.5](https://github...

It was discovered that the ld.so.cache in images generated by apko had file system permissions mode `0666`: ``` bash-5.3# find / -type f -perm -o+w /etc/ld.so.cache ``` This issue was introduced in commit [04f37e2 ("generate /etc/ld.so.cache (#1629)")](https://github.com/chainguard-dev/apko/commit/04f37e2d50d5a502e155788561fb7d40de705bd9)([v0.27.0](https://github.com/chainguard-dev/apko/releases/tag/v0.27.0)). ### Impact This potentially allows a local unprivileged user to add additional additional directories including dynamic libraries to the dynamic loader path. A user could exploit this by placing a malicious library in a directory they control. ### Patches This issue was addressed in apko in [aedb077 ("fix: /etc/ld.so.cache file permissions (#1758)")](https://github.com/chainguard-dev/apko/commit/aedb0772d6bf6e74d8f17690946dbc791d0f6af3) ([v0.29.5](https://github.com/chainguard-dev/apko/releases/tag/v0.29.5)). ### Acknowledgements Many thanks to Cody Harris from [H2O.ai](htt...

### Summary A bug in Wasmtime's implementation of the WASIp1 set of import functions can lead to a WebAssembly guest inducing a panic in the host (embedder). The specific bug is triggered by calling `path_open` after calling `fd_renumber` with either: - two equal argument values - second argument being equal to a previously-closed file descriptor number value The corrupt state introduced in `fd_renumber` will lead to the subsequent opening of a file descriptor to panic. This panic cannot introduce memory unsafety or allow WebAssembly to break outside of its sandbox, however. There is no possible heap corruption or memory unsafety from this panic. This bug is in the implementation of Wasmtime's `wasmtime-wasi` crate which provides an implementation of WASIp1. The bug requires a specially crafted call to `fd_renumber` in addition to the ability to open a subsequent file descriptor. Opening a second file descriptor is only possible when a preopened directory was provided to the guest, ...

Researchers discovered a novel phishing attack that serves the victim a QR code as part of supposed multifactor authentication (MFA), in order to get around FIDO-based protections.

Cybersecurity researchers have shed light on a mobile forensics tool called Massistant that's used by law enforcement authorities in China to gather information from seized mobile devices. The hacking tool, believed to be a successor of MFSocket, is developed by a Chinese company named SDIC Intelligence Xiamen Information Co., Ltd., which was formerly known as Meiya Pico. It specializes in the

An attacker can pass a malicious malformed token which causes unexpected memory to be consumed during parsing.
