glibc: glibc: Denial of Service via iconv() function with specific character sets

A flaw was found in glibc, the GNU C Library. A remote attacker could exploit this vulnerability by providing specially crafted inputs using the IBM1390 or IBM1399 character sets to the iconv function. This could lead to an assertion failure, causing the application to crash and resulting in a...

Moderate: glibc security update

The glibc packages provide the standard C libraries libc, POSIX thread libraries libpthread, standard math libraries libm, and the name service cache daemon nscd used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fixes: glibc:...

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 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

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

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

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 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

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

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

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

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...
