CVE-2021-33574

CVE-2021-33574 affects the GNU C Library (glibc) mq_notify function in versions 2.32 and 2.33, where a notification thread attributes object passed via struct sigevent may be freed by the caller and then used, causing denial of service (crash) or other impact. Connected advisories confirm this is...

Denial Of Service (DoS)

glibc is vulnerable to denial of service. An attacker capable of supplying a malicious sequence of characters to an application using iconv to convert from ISO-2022-JP-3 to cause an assertion failure...

Denial Of Service (DoS)

glibc is vulnerable to denial of service. The vulnerability exists when processing invalid multi-byte input sequences which could lead to an infinite loop in applications causing the system to crash...

Arbitrary Code Execution

glibc is vulnerable to arbitrary code execution. A heap-based buffer over-read in proceednextnode in posix/regexec.c allows an attacker to execute arbitrary code on the host OS via an attempted case-insensitive regular-expression match...

[SECURITY] Fedora 33 Update: glibc-2.32-6.fc33

The glibc package contains standard libraries which are used by multiple programs on the system. In order to save disk space and memory, as well as to make upgrading easier, common system code is kept in one place and shared between programs. This particular package contains the most important se...

glibc: iconv program can hang when invoked with the -c option

The iconv program in the GNU C Library aka glibc or libc6 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, leading to a denial of service...

glibc: Assertion failure in ISO-2022-JP-3 gconv module related to combining characters

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...
