15 Synopsis
16 ========
17
18 Multiple vulnerabilities have been discovered in OpenSSL, the worst of
19 which could result in remote code execution.
20
21 Background
22 ==========
23
24 OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
25 (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
26 purpose cryptography library.
27
28 Affected packages
29 =================
30
31 -------------------------------------------------------------------
32 Package / Vulnerable / Unaffected
33 -------------------------------------------------------------------
34 1 dev-libs/openssl < 3.0.7:0/3 >= 3.0.7:0/3
35
36 Description
37 ===========
38
39 Multiple buffer overflows exist in OpenSSL's handling of TLS
40 certificates for client authentication.
41
42 Impact
43 ======
44
45 It is believed that, while unlikely, code execution is possible in
46 certain system configurations.
47
48 Workaround
49 ==========
50
51 Users operating TLS servers may consider disabling TLS client
52 authentication, if it is being used, until fixes are applied.
53
54 Resolution
55 ==========
56
57 All OpenSSL 3 users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=dev-libs/openssl-3.0.7"
