CVE-2025-12801 [MEDIUM] CWE-279 CVE-2025-12801: A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, that allows a NFSv3 client to escalate the privileges assigned to it in the /etc/exports file at mount time. In particular, it allows the client to access any subdirectory or subtree of an exported directory, regardless of the set file permissions, a

CVE-2018-20784 [CRITICAL] CWE-835 CVE-2018-20784: In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attack In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load.

CVE-2026-3633 [MEDIUM] CWE-93 CVE-2026-3633: A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the `soup_mes A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the `soup_message_new()` function, could inject arbitrary headers and additional request data. This vulnerability, known as CRLF (Carriage Return Line Feed) injection, occurs because the method value is not properly escaped during request line construction, potential

CVE-2013-1591 [CRITICAL] CWE-190 CVE-2013-1591: Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other produc Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other products, has unspecified impact and context-dependent attack vectors. NOTE: this issue might be resultant from an integer overflow in the fast_composite_scaled_bilinear function in pixman-inlines.h, which triggers an infinite loop.

CVE-2017-5440 [CRITICAL] CWE-416 CVE-2017-5440: A use-after-free vulnerability during XSLT processing due to a failure to propagate error conditions A use-after-free vulnerability during XSLT processing due to a failure to propagate error conditions during matching while evaluating context, leading to objects being used when they no longer exist. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 5

CVE-2017-2590 [HIGH] CWE-732 CVE-2017-2590: A vulnerability was found in ipa before 4.4. IdM's ca-del, ca-disable, and ca-enable commands did no A vulnerability was found in ipa before 4.4. IdM's ca-del, ca-disable, and ca-enable commands did not properly check the user's permissions while modifying CAs in Dogtag. An authenticated, unauthorized attacker could use this flaw to delete, disable, or enable CAs causing various denial of service problems with certificate issuance, OCSP signing, and de

CVE-2017-5454 [HIGH] CWE-200 CVE-2017-5454: A mechanism to bypass file system access protections in the sandbox to use the file picker to access A mechanism to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
