TITLE

Expat  calculation error vulnerability in

DESCRIPTION

In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). Expat ( alias libexpat) contains a computational error vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. No detailed vulnerability details were provided at this time. Summary: OpenShift Serverless version 1.22.0 contains a moderate security impact. This release includes security and bug fixes and enhancements. For more information, see the documentation linked in the Solution section. Security Fixes in this release include: * golang: archive/zip: Reader.Open panics on empty string (CVE-2021-41772) * golang: debug/macho: invalid dynamic symbol table command can cause panic (CVE-2021-41771) For more details about the security issues, including the impact, a CVSS score, acknowledgments, and other related information refer to the CVE pages linked in the References section. Bugs fixed (https://bugzilla.redhat.com/): 2020725 - CVE-2021-41771 golang: debug/macho: invalid dynamic symbol table command can cause panic 2020736 - CVE-2021-41772 golang: archive/zip: Reader.Open panics on empty string 5.
