Astra Linux – Vulnerability in glibc

NSCD: Stack-based buffer overflow in netgroup cache If the fixed-size cache of the Name Service Cache Daemon nscd is exhausted due to client requests, then a subsequent client request for netgroup data may lead to a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cach...

Astra Linux – Vulnerability in glibc

The iconv program in the GNU C Library also known as glibc or libc6 version 2.31 and earlier, when invoked with multiple suffixes in the destination encoding TRANSLATE or IGNORE along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, resulting in a...

Astra Linux – Vulnerability in glibc

The iconv function in the GNU C Library versions 2.39 and earlier may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set. This could potentially cause an application to crash or overwrite a neighboring variable...

Astra Linux – Vulnerability in glibc

The iconv feature in the GNU C Library also known as glibc or libc6, up to version 2.32, may have a buffer over-read issue when processing invalid multi-byte input sequences in the EUC-KR encoding...

Astra Linux – Vulnerability in glibc

Before version 2.32, the GNU C Library also known as glibc or libc6 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contained a non-canonical bit pattern. This issue was observed when passing a value of 0x5d414141414141410000 to the sinl...

Astra Linux – Vulnerability in glibc

A out-of-bounds write vulnerability was discovered in glibc before version 2.31, when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution...

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 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...

Astra Linux – Vulnerability in glibc

The iconv function in the GNU C Library also known as glibc or libc6 version 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially leading to a denial of service...

Astra Linux – Vulnerability in glibc

NSCD: The NetGroup Cache may terminate the daemon due to a memory allocation failure. The NetGroup Cache Daemon’s NSCD netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. This flaw...

Astra Linux – Vulnerability in glibc

There exists an exploitable signed comparison vulnerability in the ARMv7 memcpy implementation of GNU glibc 2.30.9000. Calling memcpy on ARMv7 targets that utilize the GNU glibc implementation with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attack...

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...

CVE-2026-89092

The nscd service in the GNU C Library 2.3.4 onwards may crash due to a stack overflow when a malicious DNS server returns too large a response for a DNS query, resulting in degraded DNS resolution for the system. Exploitation of this bug needs a system that has nscd enabled and using an untrusted...
