Gentoo Linux Security Advisory
Title: Mozilla Network Security Service: Remote execution of arbitrary code (GLSA 200703-22)
Severity: normal
Exploitable: remote
Date: March 20, 2007
Bug(s): #165555
ID: 200703-22
Synopsis
The Mozilla Network Security Services libraries are vulnerable to two buffer overflows that could result in the remote execution of arbitrary code.
Background
The Mozilla Network Security Service is a library implementing security features like SSL v2/v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME and X.509 certificates.
Affected Packages
Package: dev-libs/nss
Vulnerable: < 3.11.5
Unaffected: >= 3.11.5
Architectures: All supported architectures
Description
iDefense has reported two potential buffer overflow vulnerabilities found by researcher "regenrecht" in the code implementing the SSLv2 protocol.
Impact
A remote attacker could send a specially crafted SSL master key to a server using NSS for the SSLv2 protocol, or entice a user to connect to a malicious server with a client-side application using NSS like one of the Mozilla products. This could trigger the vulnerabilities and result in the possible execution of arbitrary code with the rights of the vulnerable application.
Workaround
Disable the SSLv2 protocol in the applications using NSS.
Resolution
All NSS users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/nss-3.11.5" |
