Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU7564
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7186
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
Update the affected package pcre to version 8.41-1.
Vulnerable software versionsArch Linux: All versions

EUVDB-ID: #VU7565
Risk: Low
CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2017-7244
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
Update the affected package pcre to version 8.41-1.

EUVDB-ID: #VU7566
Risk: Medium
CVSSv3.1: 7.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7245
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package pcre to version 8.41-1.
