SB2018080217 - Fedora 28 update for mingw-glib2, mingw-glibmm24

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2017-7186)

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

The weakness exists due to a segmentation violation issue by the libpcre1 and libpcre2. A remote attacker can send specially crafted packets and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

2) Out-of-bounds read (CVE-ID: CVE-2017-7244)

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

The weakness exists due to invalid memory read flaw in the _pcre32_xclass function in pcre_xclass.c. A remote attacker can trick the victim into loading a specially crafted file and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

3) Buffer overflow (CVE-ID: CVE-2017-7245)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error in pcre32_copy_substring() function in pcre_get.c in libpcre1 in PCRE 8.40. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Buffer overflow (CVE-ID: CVE-2017-7246)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error in pcre32_copy_substring() function in pcre_get.c in libpcre1 in PCRE 8.40. A remote unauthenticated attacker can create a specially crafted file, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Uncontrolled Recursion (CVE-ID: CVE-2017-11164)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to uncontrolled recursion when processing regular expressions in the match function in pcre_exec.c. A remote attacker can perform a denial of service attack.
