Mozilla: Memory safety bugs fixed in Firefox 71 and Firefox ESR 68.3

Mozilla developers reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. 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 Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

Mozilla: Use-after-free when retrieving a document in antitracking

Under certain conditions, when retrieving a document from a DocShell in the antitracking code, a race condition could cause a use-after-free condition and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

Mozilla: Use-after-free when performing device orientation checks

Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

Mozilla: Buffer overflow in plain text serializer

The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.

kernel: buffer-overflow hardening in WiFi beacon validation code.

An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow.

pam-python before 1.0.7-1 has an issue in regard to the default environment variable handling of Python, which could allow for local root escalation in certain PAM setups.

kernel: vulnerability in rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information

In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized.

ImageMagick: memory leak in coders/dot.c

ImageMagick 7.0.8-43 has a memory leak in coders/dot.c, as demonstrated by PingImage in MagickCore/constitute.c.

ImageMagick: memory leak in Huffman2DEncodeImage in coders/ps2.c

ImageMagick 7.0.8-40 has a memory leak in Huffman2DEncodeImage in coders/ps2.c.

ImageMagick: memory leak in coders/dot.c

ImageMagick 7.0.8-35 has a memory leak in coders/dot.c, as demonstrated by AcquireMagickMemory in MagickCore/memory.c.

ImageMagick: memory leak in coders/dps.c

ImageMagick 7.0.8-35 has a memory leak in coders/dps.c, as demonstrated by XCreateImage.

ImageMagick: memory leak in magick/xwindow.c

ImageMagick 7.0.8-35 has a memory leak in magick/xwindow.c, related to XCreateImage.

file-roller: path traversal vulnerability via a specially crafted filename contained in malicious archive

An issue was discovered in GNOME file-roller before 3.29.91. It allows a single ./../ path traversal via a filename contained in a TAR archive, possibly overwriting a file during extraction.

SPIP before 3.1.11 and 3.2 before 3.2.5 provides different error messages from the password-reminder page depending on whether an e-mail address exists, which might help attackers to enumerate subscribers.

SPIP before 3.1.11 and 3.2 before 3.2.5 mishandles redirect URLs in ecrire/inc/headers.php with a %0D, %0A, or %20 character.

SPIP before 3.1.11 and 3.2 before 3.2.5 allows prive/formulaires/login.php XSS via error messages.

SPIP before 3.1.11 and 3.2 before 3.2.5 allows authenticated visitors to modify any published content and execute other modifications in the database. This is related to ecrire/inc/meta.php and ecrire/inc/securiser_action.php.

OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 is prone to a signature-bypass vulnerability with multiple From: addresses, which might affect applications that consider a domain name to be relevant to the origin of an e-mail message.

wpa_supplicant: AP mode PMF disconnection protection bypass

hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range.
