modules/loaders/loader_ico.c in imlib2 1.6.0 has an integer overflow (with resultant invalid memory allocations and out-of-bounds reads) via an icon with many colors in its color map.

An issue was discovered on Samsung mobile devices with P(9.0) (Exynos chipsets) software. The S.LSI Wi-Fi drivers have a buffer overflow. The Samsung ID is SVE-2020-16906 (May 2020).

tcprewrite in Tcpreplay through 4.3.2 has a heap-based buffer over-read during a get_c operation. The issue is being triggered in the function get_ipv6_next() at common/get.c.

dovecot: Crash due to assert in RPA implementation

In Dovecot before 2.3.11.3, sending a specially formatted RPA request will crash the auth service because a length of zero is mishandled.

dovecot: Out of bound reads in dovecot NTLM implementation

In Dovecot before 2.3.11.3, sending a specially formatted NTLM request will crash the auth service because of an out-of-bounds read.

kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in drivers/net/wireless/marvell/mwifiex/wmm.c

An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591.

kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in drivers/net/wireless/marvell/mwifiex/scan.c

An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea.

Phoenix Contact Automation Worx <= 1.87: out-of-bounds read remote code execution

mwe file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier is vulnerable to out-of-bounds read remote code execution. Manipulated PC Worx projects could lead to a remote code execution due to insufficient input data validation.

Phoenix Contact Automation Worx <= 1.87: stack-based overflow

PLCopen XML file parsing in Phoenix Contact PC Worx and PC Worx Express version 1.87 and earlier can lead to a stack-based overflow. Manipulated PC Worx projects could lead to a remote code execution due to insufficient input data validation.

The frame touch module does not make validity judgments on parameter lengths when processing specific parameters,which caused out of the boundary when memory access.The vulnerability eventually leads to a local DOS on the device.

kernel: buffer overflow in mt76_add_fragment function in drivers/net/wireless/mediatek/mt76/dma.c

An array overflow was discovered in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c in the Linux kernel before 5.5.10, aka CID-b102f0c522cf. An oversized packet with too many rx fragments can corrupt memory of adjacent pages.

Mozilla: Memory safety bugs fixed in Thunderbird 78

Mozilla developers and community members reported memory safety bugs present in Firefox 77. 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 < 78.

Mozilla: Out of bound read in Date.parse()

Due to confusion processing a hyphen character in Date.parse(), a one-byte out of bounds read could have occurred, leading to potential information disclosure. This vulnerability affects Firefox < 78.

Mozilla: Information disclosure due to manipulated URL object

Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.

Mozilla: Memory safety bugs fixed in Firefox 77 and Firefox ESR 68.9

Mozilla developers reported memory safety bugs present in Firefox 76 and 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. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.

Mozilla Developer Nicolas Silva found that when using WebRender, Firefox would under certain conditions leak arbitrary GPU memory to the visible screen. The leaked memory content was visible to the user, but not observable from web content. This vulnerability affects Firefox < 77.

nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read

A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest threat from this vulnerability is to confidentiality and system availability.

Mozilla: Memory safety bugs fixed in Firefox 76

Mozilla developers and community members reported memory safety bugs present in Firefox 75. 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 < 76.
