Updated php packages fix a security vulnerability

Publication date: 16 Oct 2020
Modification date: 16 Oct 2020
Type: security
Affected Mageia releases : 7
CVE: CVE-2020-7070

Description

In PHP versions 7.2.x when PHP is processing incoming HTTP cookie values, the
cookie names are url-decoded. This may lead to cookies with prefixes
like __Host confused with cookies that decode to such prefix, thus leading to
an attacker being able to forge cookie which is supposed to be secure. 
(CVE-2020-7070)

These updated packages also fix several bugs:
Core:
- realpath() erroneously resolves link to link
- Stack use-after-scope in define()
- getimagesize function silently truncates after a null byte
- Memleak when coercing integers to string via variadic argument

Fileinfo: finfo_file crash (FILEINFO_MIME)

LDAP: Fixed memory leaks.

OPCache: opcache.file_cache causes SIGSEGV when custom opcode handlers changed.

Standard: Memory leak in str_replace of empty string
