nginx: NGINX: Denial of Service or Code Execution via specially crafted MP4 files

A flaw was found in NGINX's ngxhttpmp4module. This Out-of-Bounds Read/Write vulnerability occurs due to improper handling of specially crafted MP4 files. A local authenticated attacker, by supplying a malicious MP4 file, can trigger a buffer over-read or overwrite in worker memory. This can lead ...

CLSA-2026-1775749004 ImageMagick: Fix of 4 CVEs

CVE-2026-25968: stack buffer overflow in MSL image-processing language via WriteMSLImage recursion - CVE-2026-25897: out-of-bounds heap write in SUN decoder on 32-bit systems via integer overflow in pixel buffer allocation - CVE-2025-53014: out-of-bounds read in InterpretImageFilename when...

UBUNTU-CVE-2026-5444

A heap buffer overflow vulnerability exists in the PAM image parsing logic. When Orthanc processes a crafted PAM image embedded in a DICOM file, image dimensions are multiplied using 32-bit unsigned arithmetic. Specially chosen values can cause an integer overflow during buffer size calculation,...

ruby: Unsafe use of alloca in rb_str_format()

The rbstrformat function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662,...

ruby: off-by-one stack-based buffer overflow in the encodes() function

Off-by-one error in the encodes function in pack.c in Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when using certain format string specifiers, allows context-dependent attackers to cause a denial of service segmentation fault via vectors that trigger a stack-based buffer overflow...

archive/tar: golang: Go's archive/tar package: Denial of Service via maliciously-crafted archive

A flaw was found in Go's archive/tar package. A remote attacker could exploit this vulnerability by providing a maliciously-crafted archive file. When the tar.Reader processes an archive containing a large number of sparse regions in the "old GNU sparse map" format, it can lead to unbounded memor...
