MGASA-2021-0048 - Updated perl-DBI packages fix security vulnerabilities

Publication date: 22 Jan 2021
Type: security
Affected Mageia releases: 7
CVE: CVE-2019-20919,

An issue was discovered in the DBI module before 1.643 for Perl. The
hv_fetch() documentation requires checking for NULL and the code does that.
But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer
dereference. (CVE-2019-20919).

An untrusted pointer dereference flaw was found in Perl-DBI < 1.643. A local
attacker who is able to manipulate calls to dbd_db_login6_sv() could cause
memory corruption, affecting the service's availability. (CVE-2020-14392).

A buffer overflow was found in perl-DBI < 1.643 in DBI.xs. A local attacker
who is able to supply a string longer than 300 characters could cause an
out-of-bounds write, affecting the availability of the service or integrity
of data. (CVE-2020-14393).
