Package : pcre2 Version : 10.32-5+deb10u1 CVE ID : CVE-2019-20454 CVE-2022-1586 CVE-2022-1587 Debian Bug : 1011954

Multiple out-of-bounds read vulnerabilities were found in pcre2, a Perl Compatible Regular Expression library, which could result in information disclosure or denial or service.

CVE-2019-20454

Out-of-bounds read when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode.

CVE-2022-1586

Out-of-bounds read involving unicode property matching in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.

CVE-2022-1587

Out-of-bounds read affecting recursions in JIT-compiled regular expressions caused by duplicate data transfers.

This upload also fixes a subject buffer overread in JIT when UTF is disabled and \X or \R has a greater than 1 fixed quantifier. This issue was found by Yunho Kim.

For Debian 10 buster, these problems have been fixed in version 10.32-5+deb10u1.

We recommend that you upgrade your pcre2 packages.
