ImageSharp: ICC CLUT parsing allocates from unvalidated channel and grid dimensions

Summary A malformed embedded ICC profile can make ImageSharp allocate memory from attacker-controlled CLUT channel and grid dimensions before verifying that the declared CLUT values are present. In published v1 through v3 packages, the public lazy ICC parser allocates approximately 115 MB from th...

EUVD-2026-94554

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, flatCols expands file-loaded column ranges without validating Min and Max against the worksheet column limit. SetColWidth reaches flatCols, which expands xlsxCol.Min through xlsxCol.Max...

CVE-2026-107215

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.3.1 to 2.11.0, extractPart allocates a byte slice directly from an attacker-controlled CFB directory-entry size before validating the sector chain or size domain. extractPart trusts the CFB directory...

Security Bulletin:body-parser Limit Validation Vulnerability in Versions Prior to 1.20.6 and 2.3.0

Summary Impact: In body-parser versions prior to 1.20.6 1.x line and 2.3.0 2.x line, when the parser is configured with an invalid limit option value such as an unparseable string or NaN, bytes.parse returns null and the request body size check is silently skipped. Applications that rely on limit...

Security Bulletin:Inconsistent Enforcement of MaxNumberLength in Jackson-Core Async JSON Parser, Leading to DoS

Summary The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in StreamReadConstraints default: 1000 characters. An attacker able to submit JSON to an application that uses the async parser API can supply a number token of arbitrary...

CVE-2026-106578

A flaw was found in ImageMagick. This vulnerability can lead to a Denial of Service DoS when the software processes untrusted input. A remote attacker could submit a specially crafted image file that triggers an invalid memory free condition in the Magick Vector Graphics MVG decoder, causing the...

CVE-2026-106571

A flaw was found in ImageMagick. A local attacker can cause a Denial of Service DoS by issuing a specially crafted call to the GetVirtualPixels function. An integer calculation error allows data to be written beyond allocated heap memory boundaries, resulting in an unexpected process crash...

CVE-2026-93524

A flaw was found in xorg-x11-server. An authenticated local user can trigger an out-of-bounds heap memory read by sending specially crafted X Keyboard Extension XKB requests with inconsistent key range parameters. This flaw leads to information disclosure, allowing the user to read sensitive data...

CVE-2026-80877

A flaw was found in the Linux kernel's AFS Andrew File System module. This vulnerability occurs in the afsupdatecell function when it attempts to update a volume list vllist that is empty. Under specific conditions, the old vllist is not properly released, leading to a memory leak. A local attack...

CVE-2026-80843

A flaw was found in the Linux kernel's xfrm IPSec framework component. This vulnerability occurs when the xfrmstateconstruct function incorrectly manages memory allocations for authentication algorithms. Specifically, it can overwrite an existing allocation, leading to a memory leak. Over time,...

CVE-2026-80811

A flaw was found in the Linux kernel's iouring/cmd component. This vulnerability allows for a memory leak due to iovec arrays not being properly freed when asynchronous commands are not recycled. An attacker could potentially exploit this by triggering specific workloads, such as NVMe passthrough...

CVE-2026-80797

A flaw was found in the Near Field Communication NFC PN533 driver in the Linux kernel. When a PN533 device is removed while data fragments are still queued, the driver's cleanup process fails to properly release these fragments, resulting in a memory leak. This can lead to system instability or...

CVE-2026-80784

A flaw was found in the Linux kernel's Multipath TCP MPTCP component. A race condition exists during socket teardown and concurrent userspace Multipath TCP MPTCP general announce operations. This can allow a local attacker to trigger a memory leak by causing an allocation to occur after a list ha...

Updated tesseract packages fix security vulnerabilities

This is a security update. It fixes nine vulnerabilities in tesseract, the OCR text recognition engine. All nine can be triggered only by feeding tesseract a maliciously crafted input file: either a specially crafted recognition/language data file .traineddata or a crafted word-list file. Dependi...
