CVE-2021-3326 – glibc: Assertion failure in ISO-2022-JP-3 gconv module related to combining characters
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.

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.

CVE-2019-25013 – glibc: buffer over-read in iconv when processing invalid multi-byte input sequences in the EUC-KR encoding
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.

CVE-2020-1752 – glibc: use-after-free in glob() function when expanding ~user
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 •
