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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202209-24 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Expat: Multiple Vulnerabilities Date: September 29, 2022 Bugs: #791703, #830422, #831918, #833431, #870097 ID: 202209-24 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Multiple vulnerabilities have been discovered in Expat, the worst of which could result in arbitrary code execution.
