Astra Linux – Vulnerability in glibc

The Name Service Cache Daemon’s nscd netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. This flaw was introduced in glibc 2.15, when the cache was added to nscd. This vulnerability only exists in the nscd binary...

Astra Linux – Vulnerability in glibc

The deprecated compatibility function clntcreate in the sunrpc module of the GNU C Library also known as glibc from versions up to 2.34 copies its hostname argument onto the stack without validating its length. This may lead to a buffer overflow, potentially causing a denial of service or, if the...

Astra Linux – Vulnerability in glibc

The mqnotify function in the GNU C Library also known as glibc versions 2.32 and 2.33 has a use-after-free vulnerability. It may access the notification thread attributes object passed through its struct sigevent parameter after it has been freed by the caller, resulting in a denial of service...

Astra Linux – Vulnerability in glibc

The iconv function in the GNU C Library also known as glibc or libc6 versions 2.32 and earlier, when processing invalid multi-byte input sequences in encodings such as IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399, fails to advance the input state properly. This can lead to an infinite loop in...

Astra Linux – Vulnerability in glibc

The deprecated compatibility function svcunixcreate in the sunrpc module of the GNU C Library aka glibc from version 2.34 onwards copies the path argument onto the stack without validating its length. This may lead to a buffer overflow, potentially causing a denial of service or, if the applicati...

CVE-2026-19542: Stack-based Buffer Overflow

Calling tdelete on a sufficiently deep tree in the GNU C Library version 2.1 to 2.44 may write one pointer past the end of an alloca-allocated array on the stack, which may crash the application. The tdelete implementation keeps an explicit stack of parent nodes for rebalancing, which is grown as...

CVE-2026-19499: Heap-based Buffer Overflow

Calling strfmon and strfmonl in the GNU C Library version 2.38 to 2.44 can write past the end of the caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires an application code path that calls strfmon or strfmonl with right-justified width padding...

EUVD-2026-77053

A vulnerability was determined in davenardella snap7 up to 1.4.3. The affected element is the function TSnap7MicroClient::opUpload of the file src/core/s7microclient.cpp. Executing a manipulation of the argument DataLen can lead to memory corruption. The attack can be executed remotely. The explo...

[SECURITY] Fedora 43 Update: mingw-expat-2.8.4-1.fc43

This is expat, the C library for parsing XML, written by James Clark. Expat is a stream oriented XML parser. This means that you register handlers with the parser prior to starting the parse. These handlers are called when the parser discovers the associated structures in the document being parse...
