Description

This security bulletin contains information about 5 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2017-11145)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information.

The weakness exists due to out-of-bounds read in timelib_meridian(). A remote attacker can read arbitrary data on the target system.

2) Null pointer dereference (CVE-ID: N/A)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to null pointer dereference in zend_mm_alloc_small(). A remote attacker can cause the application to crash.

3) Infinite loop (CVE-ID: N/A)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to infinite loop when printing an error-message. A remote attacker can cause the application to crash.

4) Out-of-bounds read (CVE-ID: CVE-2017-16642)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to out-of-bounds read in timelib_meridian(). A remote attacker can cause the application to crash.

5) Denial of service (CVE-ID: N/A)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to data corruption when reading fields of bit type. A remote attacker can cause the application to crash.
