https://notcve.org/view.php?id=CVE-2021-3326
The iconv function in the GNU C Library (aka glibc or libc6) 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 resulting in a denial of service. La función iconv en la biblioteca GNU C (también se conoce como glibc o libc6) versiones 2.32 y anteriores, cuando procesa secuencias de entrada no válidas en la codificación ISO-2022-JP-3, se produce un fallo una aserción en la ruta del código y aborta el programa, potencialmente resultando en una denegación de servicio A flaw was found in glibc's iconv() functionality. This flaw allows an attacker capable of supplying a crafted sequence of characters to an application using iconv() to convert from ISO-2022-JP-3 to cause an assertion failure. The highest threat from this vulnerability is to system availability. • http://www.openwall.com/lists/oss-security/2021/01/28/2 https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202107-07 https://security.netapp.com/advisory/ntap-20210304-0007 https://sourceware.org/bugzilla/show_bug.cgi?id=27256 https://sourceware.org/git/?p=glibc.git%3Ba=commit%3Bh=7d88c6142c6efc160c0ee5e4f85cde382c072888 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https:/ • CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2019-25013
The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read. La funcionalidad iconv en la biblioteca GNU C (también se conoce como glibc o libc6) versiones hasta 2.32, cuando se procesan secuencias de entrada multibyte no válidas en la codificación EUC-KR, puede tener una lectura excesiva del búfer. A flaw was found in glibc. When processing input in the EUC-KR encoding, an invalid input sequence could cause glibc to read beyond the end of a buffer, resulting in a segmentation fault.

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2020-29573 – glibc: stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern
https://notcve.org/view.php?id=CVE-2020-29573
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference. El archivo sysdeps/i386/ldbl2mpn.c en la GNU C Library (también se conoce como glibc o libc6) versiones anteriores a 2.23 en objetivos x86 presenta un desbordamiento de búfer en la región stack de la memoria si la entrada a cualquiera de la familia funciones printf es un doble longitud de 80 bits con un patrón de bits no canónico, como se ve al pasar un valor \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 a sprintf. NOTA: la cuestión no afecta a la glibc por defecto en 2016 o más tarde (es decir, 2,23 o más tarde), debido a los compromisos contraídos en 2015 para alinear las funciones matemáticas del C99 mediante el uso de los elementos incorporados del GCC. • https://security.gentoo.org/glsa/202101-20 https://security.netapp.com/advisory/ntap-20210122-0004 https://sourceware.org/bugzilla/show_bug.cgi?id=26649 https://sourceware.org/pipermail/libc-alpha/2020-September/117779.html https://access.redhat.com/security/cve/CVE-2020-29573 https://bugzilla.redhat.com/show_bug.cgi?id=1905213 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-1752
A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. Una vulnerabilidad de uso de la memoria previamente liberada introducida en glibc versiones anteriores a la versión 2.14, se descubrió en la manera en que se llevó a cabo la expansión de tilde. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1752 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202101-20 https://security.netapp.com/advisory/ntap-20200511-0005 https://sourceware.org/bugzilla/show_bug.cgi?id • CWE-416: Use After Free •

An out-of-bounds write vulnerability was found in glibc before 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. The highest threat from this vulnerability is to system availability. Se encontró una vulnerabilidad de escritura fuera de límites en glibc versiones anteriores a 2.31, cuando se manejaban trampolines de señal en PowerPC. Concretamente, la función backtrace no comprueba apropiadamente los límites de la matriz cuando almacena la dirección de la trama, resultando en una denegación de servicio o a una posible ejecución de código. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1751 https://security.gentoo.org/glsa/202006-04 https://security.netapp.com/advisory/ntap-20200430-0002 https://sourceware.org/bugzilla/show_bug.cgi?id=25423 https://usn.ubuntu.com/4416-1 https://access.redhat.com/security/cve/CVE-2020-1751 https://bugzilla.redhat.com/show_bug.cgi?id=1810719 • CWE-787: Out-of-bounds Write •
