TITLE

curl  Vulnerability in resource initialization deficiency in

DESCRIPTION

curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. curl Exists in a flaw in resource initialization.Information may be obtained. 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. JIRA issues fixed (https://issues.jboss.org/): LOG-1897 - Applying cluster state is causing elasticsearch to hit an issue and become unusable LOG-1925 - [release-5.3] No datapoint for CPU on openshift-logging dashboard LOG-1962 - [release-5.3] CLO panic: runtime error: slice bounds out of range [:-1] 6. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: curl security and bug fix update Advisory ID: RHSA-2021:4511-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:4511 Issue date: 2021-11-09 CVE Names: CVE-2021-22876 CVE-2021-22898 CVE-2021-22925 ==================================================================== 1.
