  script_tag(name:"insight", value:"An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers.(CVE-2021-42574)

An out-of-bounds flaw was found in binutils' stabs functionality. The attack needs to be initiated locally where an attacker could convince a victim to read a specially crafted file that is processed by objdump, leading to the disclosure of memory and possibly leading to the execution of arbitrary code or causing the utility to crash.(CVE-2021-45078)");
