Description

Updated firefox packages fix security vulnerability Updated nss and firefox packages fix security vulnerabilities: NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys (CVE-2020-12399). Side channel vulnerabilities during RSA key generation in NSS (CVE-2020-12402). When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash due to a use-after-free (CVE-2020-12405). Mozilla developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash due to type confusion with NativeTypes. We presume that with enough effort that it could be exploited to run arbitrary code (CVE-2020-12406). Mozilla developers Tom Tung and Karl Tomlinson reported memory safety bugs present in Firefox ESR 68.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code (CVE-2020-12410). Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript (CVE-2020-12418). When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free in nsGlobalWindowInner. This could have led to memory corruption and a potentially exploitable crash (CVE-2020-12419). When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash (CVE-2020-12420). When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user (CVE-2020-12421).
