2) Memory corruption

EUVDB-ID: #VU15363

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-18258

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists in the xz_head() function of the GNOME libxml2 library, as defined in the xzlib.c source code due to boundary error in the Lempel-Ziv-Markov (LZMA) decompression feature. A remote unauthenticated attacker can trick the victim into opening a specially crafted LZMA file that submits malicious input, trigger memory corruption and cause the application to crash.

Mitigation

3) Stack-based buffer overflow

EUVDB-ID: #VU9691

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-9048

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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

The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper bounds checking in the valid.c code. A remote attacker can send a specially crafted request, trigger stack-based buffer overflow condition and cause the service to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Install update from vendor's website.
