-------------------------------------------------------------------------
Package : less Version : 487-0.1+deb10u1 CVE ID : CVE-2022-48624 CVE-2024-32487 Debian Bug : 1064293 1068938
Security vulnerabilities were found in less, a pager program similar to more, which could result in arbitrary command execution when processing files with crafted names.
CVE-2022-48624
It was discovered that LESSCLOSE handling in less did not quote shell metacharacters.
CVE-2024-32487
It was discovered that filenames containing a newline character could result in arbitrary command execution during input preprocessor invocation.
For Debian 10 buster, these problems have been fixed in version 487-0.1+deb10u1.
We recommend that you upgrade your less packages.
For the detailed security status of less please refer to its security tracker page at:
