CVE-2018-1301 [MEDIUM] CWE-119 CVE-2018-1301: A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due t A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server us

CVE-2016-3136 [MEDIUM] CVE-2016-3136: The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors.

CVE-2020-6800 [HIGH] CWE-787 CVE-2020-6800: Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firef Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. 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. In general, these flaws cannot be exploited through email in the Thunderbird product

CVE-2016-9843 [CRITICAL] CVE-2016-9843: The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unsp The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving big-endian CRC calculation.

It allows attackers to smuggle HTTP reques An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to
