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...
USN-8737-2 glibc vulnerabilities
USN-8737-1 fixed vulnerabilities in GNU C Library. This update provides the corresponding fixes for Ubuntu 24.04 LTS. Original advisory details: It was discovered that GNU C Library had a buffer overflow in the strfmon function when handling right-justification padding. An attacker could possibly...

USN-8737-1: GNU C Library vulnerabilities
It was discovered that GNU C Library had a buffer overflow in the strfmon function when handling right-justification padding. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 26.04 LTS. CVE-2026-19499 It was discover...
SUSE CVE-2026-18374
Passing an effectively empty string to the ,ccs= syntax extension of the mode argument in the fopen function in the GNU C Library version 2.45 or earlier may result in a heap buffer overflow when the mode string input to the function is attacker controlled. This usage pattern is not seen in...

Converting crafted EUC JISX0213 input to UCS-4 or the internal wide character encoding, for example with iconv, in the GNU C Library version 2.3 to 2.44 may result in the converter making no progress, causing the calling application to hang. Some EUC JISX0213 sequences decode to two code points. ...

Calling strfmon and strfmon l 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 strfmon l with right-justified width paddi...
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 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
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
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
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
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...
