GLSA 200710-06: OpenSSL: Multiple vulnerabilities
| Severity: | high |
| Title: | OpenSSL: Multiple vulnerabilities |
| Date: | 10/07/2007 |
| Bugs: | , |
| ID: | 200710-06 |
Synopsis
A buffer underflow vulnerability and an information disclosure vulnerability have been discovered in OpenSSL.Background
OpenSSL is an implementation of the Secure Socket Layer and Transport Layer Security protocols.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| dev-libs/openssl | < 0.9.8e-r3 | >= 0.9.8e-r3 | All supported architectures |
Description
Moritz Jodeit reported an off-by-one error in the SSL_get_shared_ciphers() function, resulting from an incomplete fix of CVE-2006-3738. A flaw has also been reported in the BN_from_montgomery() function in crypto/bn/bn_mont.c when performing Montgomery multiplication.
Impact
A remote attacker sending a specially crafted packet to an application relying on OpenSSL could possibly execute arbitrary code with the privileges of the user running the application. A local attacker could perform a side channel attack to retrieve the RSA private keys.
Workaround
There is no known workaround at this time.
Resolution
All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8e-r3"
