详细描述

libcroco: This package provides debug information for package libcroco. Debug information is useful when developing applications that use this package or when debugging this package.
thunderbird: Mozilla Thunderbird is a standalone mail and newsgroup client.


Security Fix(es):
libcroco: A stack overflow flaw was found in libcroco. A service using libcroco's CSS parser could be crashed by a local, authenticated attacker, or an attacker utilizing social engineering, using a crafted input. The highest threat from this vulnerability is to system availability.(CVE-2020-12825)
libcroco: bugfix
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier, resulting in memory corruption and a potentially exploitable crash.(CVE-2020-12417)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript.(CVE-2020-12418)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free condition. This could have led to memory corruption and a potentially exploitable crash.(CVE-2020-12419)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: 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)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: 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 This could have caused add-ons to become out-of-date silently without notification to the user.(CVE-2020-12421)
thunderbird: Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.(CVE-2020-6463)
thunderbird: Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream.(CVE-2020-6514)
thunderbird: By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.(CVE-2020-15652)
thunderbird: Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. 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. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.(CVE-2020-15659)
thunderbird: By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.(CVE-2020-15664)
thunderbird: When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.(CVE-2020-15669)
thunderbird: If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird sends username and password over https to a server controlled by the attacker. This vulnerability affects Thunderbird < 68.10.0.(CVE-2020-15646)
thunderbird: bugfix
