EUVDB-ID: #VU32655

Risk: Medium

CVSSv4.0: 2.7 [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:Green]

CVE-ID: CVE-2013-4130

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The (1) red_channel_pipes_add_type and (2) red_channel_pipes_add_empty_msg functions in server/red_channel.c in SPICE before 0.12.4 do not properly perform ring loops, which might allow remote attackers to cause a denial of service (reachable assertion and server exit) by triggering a network error.

Mitigation

Install update from vendor's website.
