CVE-2026-119209 pypdf: Possible large memory usage when parsing cross-reference streams

pypdf is a free and open-source pure-python PDF library. Prior to 6.21.3, pypdf can consume excessive memory while opening a crafted PDF containing cross-reference streams that declare very large entry counts. Highly compressible streams and /Prev chains can multiply the number of parsed entries...

CVE-2026-119209

The pypdf pure-python PDF library (prior to version 6.21.3 ) is vulnerable to uncontrolled resource consumption (CWE-400, CWE-770). A crafted PDF can trigger excessive memory consumption when opening cross-reference streams that declare very large entry counts. Specifically, highly compressible s...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mmc: core: Avoid negative index with array access The commit 4d0c8d0aef63 “mmc: core: Use mrq.sbc in close-ended ffu” assigns previdata = idatasi - 1, but does not check that the iterator i is greater than zero. We will fix this ...

GHSA-8JJQ-8J9W-M2V6 Excelize: RIGHT() on supplementary-plane text slices with a negative index and panics

leftRight calc.go:14236 tests the length with countUTF16String, which counts a rune above U+FFFF as 2. The RIGHT branch on 14241 then slices runetext at utf8.RuneCountInStringtext-numChars, which counts it as 1. For text with N such runes the two measures are 2N and N, so any numChars between the...

CVE-2026-107225

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.0 to 2.11.0, GetStyle's fill, border, and font extraction predicates check only upper bounds for attacker-controlled style-table indices. File.GetStyle relies on extractStyleCondFuncs predicates that...

CVE-2026-107225

The Excelize Go library (versions 2.8.0 to 2.11.0 ) is vulnerable to a denial-of-service condition due to improper input validation in the GetStyle function. The root cause is that the extraction predicates for fill, border, and font indices only check upper bounds, allowing negative values from ...

CVE-2026-81881 radare2: Heap out-of-bounds read in radare2 Mach-O Swift metadata parser

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Mach-O Swift field-metadata parser was vulnerable because a relative Swift field pointer could be lower than the field-metadata section base, making subtraction produce a negative logical inde...

Astra Linux – Vulnerability in rsync

A malicious client acting as the recipient of an rsync file transfer can trigger an out-of-bounds read of a heap-based buffer, through a negative array index. The malicious rsync client requires at least read access to the remote rsync module in order to trigger this issue...
