CVE-2006-6235 [CRITICAL] CVE-2006-6235: A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 throu A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.

CVE-2026-58379 [HIGH] CWE-122 CVE-2026-58379: A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulner A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when pr

CVE-2024-1488 [HIGH] CWE-276 CVE-2024-1488: A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outs A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potenti

CVE-2026-58381 [HIGH] CWE-415 CVE-2026-58381: A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the read_layer_ A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the read_layer_block() function when processing a specially crafted PSP file. This could allow an attacker to cause memory corruption, potentially leading to denial of service or arbitrary code execution.

CVE-2025-62230 [HIGH] CWE-416 CVE-2025-62230: A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resour A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.

CVE-2017-12171 [MEDIUM] CWE-284 CVE-2017-12171: A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd 2.2.15-60, causing comme A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd 2.2.15-60, causing comments in the "Allow" and "Deny" configuration lines to be parsed incorrectly. A web administrator could unintentionally allow any client to access a restricted HTTP resource.
