http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10543 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10543 Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. Perl before 5.30.3 has an integer overflow related to mishandling of a 'PL_regkind[OP(n)] == NOTHING' situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

According to the versions of the perl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Perl before 5.30.3 has an integer overflow related to     mishandling of a 'PL_regkind[OP(n)] == NOTHING'     situation. A crafted regular expression could lead to     malformed bytecode with a possibility of instruction     injection.(CVE-2020-10878)

  - Perl before 5.30.3 on 33-bit platforms allows a     heap-based buffer overflow because nested regular     expression quantifiers have an integer     overflow.(CVE-2020-10543)

This update for perl fixes the following issues :

  - CVE-2020-10543: Fixed a heap buffer overflow in regular     expression compiler which could have allowed overwriting     of allocated memory with attacker's data (bsc#1171863).

  - CVE-2020-10878: Fixed multiple integer overflows which     could have allowed the insertion of instructions into     the compiled form of Perl regular expression     (bsc#1171864).

  - CVE-2020-12723: Fixed an attacker's corruption of the     intermediate language state of a compiled regular     expression (bsc#1171866).

  - Fixed a bad warning in features.ph (bsc#1172348).
