Summary: Several security issues were fixed in Thunderbird.
Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky,
Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, and Gary Kwong
discovered multiple memory safety issues in Thunderbird. If a user were
tricked in to opening a specially crafted message, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2015-4513)

Tyson Smith and David Keeler discovered that NSS incorrectly handled
decoding certain ASN.1 data. An remote attacker could use this issue to

CVE-2015-7182 nss: ASN.1 decoder heap overflow when decoding constructed OCTET STRING that mixes indefinite and definite length encodings (MFSA 2015-133)
Mozilla engineers David Keeler reported a buffer overflow in the ASN.1 decoder in Network Security Services (NSS). These issues were in octet string parsing and were found through fuzzing and code inspection. If these issues were exploited, they would lead to a potentially exploitable crash.
These issues were fixed in NSS version 3.19.2.1 and 3.19.4, shipped in Firefox and Firefox ESR, respectively, as well as NSS 3.20.1.

I discovered this when investigating bug 1192028. Consider the following ASN.1:
24 0A [OCTET STRING | CONSTRUCTED] [length is 10 bytes]
24 80 [OCTET STRING | CONSTRUCTED] [indefinite length]
04 01 01 [OCTET STRING] [length is 1] [value is 1]
00 00 [end of indefinite length contents marker]
04 01 02 [OCTET STRING] [length is 1] [value is 2]
If I understand correctly, this is valid ASN.1 and is equivalent to 04 02 01 02 (i.e. an OCTET STRING of length 2 with value 01 02).
However, under ASAN using a setup similar to bug 1192028 (see attached), this results in a use-after-poison that I believe could be parleyed into a heap overflow.
