CVE-2018-1000517 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2021-02-18 7.5 HIGH 9.8 CRITICAL
BusyBox project BusyBox wget version prior to commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e contains a Buffer Overflow vulnerability in Busybox wget that can result in heap buffer overflow. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in after commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e.
CVE-2019-12519 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-02-11 7.5 HIGH 9.8 CRITICAL
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.
CVE-2019-12520 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2021-02-11 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI.
CVE-2019-12524 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2021-02-09 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintainer. This rule is implemented via url_regex. The handler for url_regex rules URL decodes an incoming request. This allows an attacker to encode their URL to bypass the url_regex check, and gain access to the blocked resource.
CVE-2018-17095 2 Audio File Library Project, Canonical 2 Audio File Library, Ubuntu Linux 2021-02-09 6.8 MEDIUM 8.8 HIGH

In OpenJPEG 2.3.0, there is an integer overflow caused by an out-of-bounds left shift in the opj_j2k_setup_encoder function (openjp2/j2k.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
CVE-2018-6616 4 Canonical, Debian, Oracle and 1 more 4 Ubuntu Linux, Debian Linux, Georaster and 1 more 2021-02-03 4.3 MEDIUM 5.5 MEDIUM
In OpenJPEG 2.3.0, there is excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
CVE-2017-17480 3 Canonical, Debian, Uclouvain 3 Ubuntu Linux, Debian Linux, Openjpeg 2021-02-03 7.5 HIGH 9.8 CRITICAL
In OpenJPEG 2.3.0, a stack-based buffer overflow was discovered in the pgxtovolume function in jp3d/convert.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution.
