TITLE

GNU C Library  Vulnerabilities in the use of freed memory

DESCRIPTION

The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact. GNU C Library ( alias glibc) Is vulnerable to the use of freed memory.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. The vulnerability stems from the library's mq_notify function having a use-after-free feature. Summary: An update is now available for OpenShift Logging 5.1. Bugs fixed (https://bugzilla.redhat.com/): 1944888 - CVE-2021-21409 netty: Request smuggling via content-length header 2004133 - CVE-2021-37136 netty-codec: Bzip2Decoder doesn't allow setting size restrictions for decompressed data 2004135 - CVE-2021-37137 netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way 2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value 5.
