CVE-2018-12359

A buffer overflow can occur when rendering canvas content while adjusting the height and width of the canvas element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

Mozilla: Memory safety bugs fixed in Firefox ESR 52.9 (CVE-2018-5188).

Mozilla: Buffer overflow using computed size of canvas element (CVE-2018-12359).

Mozilla: Use-after-free using focus() (CVE-2018-12360).

Mozilla: Media recorder segmentation fault when track type is changed during capture (CVE-2018-5156).

Mozilla: Integer overflow in SSSE3 scaler (CVE-2018-12362).

Mozilla: Use-after-free when appending DOM nodes (CVE-2018-12363).

Mozilla: CSRF attacks through 307 redirects and NPAPI plugins (CVE-2018-12364).

Mozilla: Compromised IPC child process can list local filenames (CVE-2018-12365).

Mozilla: Invalid data handling during QCMS transformations (CVE-2018-12366).

The updated packages fix several bugs and some security issues:

Memory safety bugs fixed in Firefox 60, Firefox ESR 60.1, Firefox ESR 52.9, and Thunderbird 52.9. (CVE-2018-5188)

The signature verification routine in Enigmail before 2.0.7 interprets user ids as status/control messages and does not correctly keep track of the status of multiple signatures, which allows remote attackers to spoof arbitrary email signatures via public keys containing crafted primary user ids. (CVE-2018-12019)

mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. (CVE-2018-12020)
