JPEG XL vs AVIF for web use-cases

JPEG XL has now landed in all major browsers, so I figured I'd take a closer look at what it's good/bad at compared to other formats. Conclusions I'll go into full detail, with examples and benchmarks, but for those of you who don't have the time, here are the headlines: For lossy photos on the...

GHSA-R7X5-4969-99P7 Excelize: Nil-pointer dereference in GetSlicers when a worksheet has extLst present but no drawing element

Summary GetSlicers guards only if ws.ExtLst == nil return slicer.go:816-818 and then immediately dereferences ws.Drawing.RID with no nil check on ws.Drawing itself. Drawing and ExtLst are two independently optional child elements of in xl/worksheets/sheetN.xml, populated separately by encoding/xm...

Excelize: Panic in cellInRange on a worksheet with an empty mergeCell ref

Summary A worksheet containing makes mergeCellsParser leave the cached rectangle empty, and cellInRange then indexes that empty slice without a length check. Every non-streaming cell API panics with index out of range 0 with length 0 on the first cell read after opening the file. Where it is...

Excelize: Unbounded <col max> attribute is loaded with no MaxColumns check and expanded per-column by flatCols(), so any column mutator hangs or OOMs the process

Summary The max attribute of a element in xl/worksheets/sheetN.xml is read verbatim on open with no check against MaxColumns, and flatCols then walks Min..Max doing a deepcopy.Copy and append per iteration. Executed: max="300000", only about 18x past the real 16384 limit, cost 46.2 s of CPU and 1...

Excelize: GetStyle panics on a negative fillId, borderId or fontId in styles.xml

Summary File.GetStyle indexes the fill, border and font tables with values taken straight out of xl/styles.xml, and the conditions gating those lookups check only the upper bound. A workbook whose cellXfs entry carries fillId="-1", borderId="-1" or fontId="-1" reaches a negative slice index and...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The mcbausb driver lacks the implementation of netdeviceops-ndochangemtu, which prevents buffer overflows. Sending a PFPACKET message allows bypassing the CAN driver’s logic and directly reaching the xmit function. The only check...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The sun4iCan driver does not populate the ndochangemtu function, allowing for a buffer overflow. Sending a PFPACKET message allows bypassing the CAN driver’s logic and directly reaching the xmit function of the CAN driver. The on...

SUSE CVE-2025-12121

Lite XL versions 2.1.8 and prior contain a vulnerability in the system.exec function, which allowed arbitrary command execution through unsanitized shell command construction. This function was used in project directory launching core.lua, drag-and-drop file handling rootview.lua, and the "open i...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The can: hi311x module has corrected the ndochangemtu function to prevent buffer overflows. Sending a PFPACKET allows bypassing the CAN driver’s logic and directly reaching the xmit function of the CAN driver. The only check...

Forging Tree-Ring: Reproducing and Instrumenting Black-Box Semantic Watermark Forgery

Semantic watermarking schemes such as Tree-Ring hide a detectable pattern in the initial noise latent of a diffusion model. Recent work shows these watermarks are not only removable but forgeable: an attacker who never sees the watermarking key can still produce images the genuine detector accept...
