re2c 1.3 has a heap-based buffer overflow in Scanner::fill in parse/scanner.cc via a long lexeme.
2 CVE-2020-11945 190 Exec Code Overflow 2020-04-23 2021-03-17

None Remote Low Not required Partial Partial Partial
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).

libfreerdp/gdi/region.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Integer Overflow.
4 CVE-2020-11058 119 Overflow 2020-05-12 2020-09-01
3.5
None Remote Medium ??? None None Partial
In FreeRDP after 1.1 and before 2.0.0, a stream out-of-bounds seek in rdp_read_font_capability_set could lead to a later out-of-bounds read. As a result, a manipulated client or server might force a disconnect due to an invalid data read. This has been fixed in 2.0.0.
5 CVE-2020-11046 119 Overflow 2020-05-07 2020-08-30

In FreeRDP after 1.0 and before 2.0.0, there is a stream out-of-bounds seek in update_read_synchronize that could lead to a later out-of-bounds read.
6 CVE-2020-10722 190 Overflow Mem. Corr. 2020-05-19 2021-01-20
4.6
None Local Low Not required Partial Partial Partial
A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.
7 CVE-2020-8835 119 Overflow 2020-04-02 2021-07-21
7.2
None Local Low Not required Complete Complete Complete
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780)
8 CVE-2020-8450 119 Overflow 2020-02-04 2021-07-21

None Remote Low Not required Partial Partial Partial
An issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can cause a buffer overflow in a Squid instance acting as a reverse proxy.
9 CVE-2020-6831 120 Overflow Mem. Corr. 2020-05-26 2021-07-21
7.5

A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
10 CVE-2020-5312 120 Overflow 2020-01-03 2020-07-10

libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow.

libvncclient/cursor.c in LibVNCServer through 0.9.12 has a HandleCursorShape integer overflow and heap-based buffer overflow via a large height or width value. NOTE: this may overlap CVE-2019-15690.
13 CVE-2019-12521 787 Overflow 2020-04-15 2021-07-21
4.3
None Remote Medium Not required None None Partial
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.
14 CVE-2019-12519 787 Overflow 2020-04-15 2021-02-11
7.5
None Remote Low Not required Partial Partial Partial
An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.

It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow.
17 CVE-2015-9542 787 Exec Code Overflow 2020-02-24 2020-08-14
5.0
None Remote Low Not required None None Partial
add_password in pam_radius_auth.c in pam_radius 1.4.0 does not correctly check the length of the input password, and is vulnerable to a stack-based buffer overflow during memcpy(). An attacker could send a crafted password to an application (loading the pam_radius library) and crash it. Arbitrary code execution might be possible, depending on the application, C library, compiler, and other factors.
