![]() Upgrade Debian:unstable nss to version 2:3.73-1 or higher. This vulnerability affects NSS < 3.73 and NSS < 3.68.1. However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. Note: This vulnerability does NOT impact Mozilla Firefox. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 are likely to be impacted. NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. See How to fix? for Debian:unstable relevant fixed versions and status. Note: Versions mentioned in the description apply only to the upstream nss package and not the nss package as distributed by Debian. Upgrade Debian:unstable libx11 to version 2:1.7.1-1 or higher. For example, if the victim encounters malicious terminal control sequences for color codes, then the attacker may be able to take full control of the running graphical session. The user-controlled data exceeding the maximum size is then interpreted by the server as additional X protocol requests and executed, e.g., to disable X server authorization completely. ![]() ![]() The libX11 XLookupColor request (intended for server-side color lookup) contains a flaw allowing a client to send color-name requests with a name longer than the maximum size allowed by the protocol (and also longer than the maximum packet size for normal-sized packets). LookupCol.c in X.Org X through X11R7.7 and libX11 before 1.7.1 might allow remote attackers to execute arbitrary code. ![]() Note: Versions mentioned in the description apply only to the upstream libx11 package and not the libx11 package as distributed by Debian. ![]()
