What it is

The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.

CVE-2026-6695

CVE-2026-6695 - MEDIUM Severity Vulnerability

A flaw was found in GIMP. A remote attacker could exploit this by tricking a user into opening a specially crafted PAA (Paint Shop Pro Array) image file. This vulnerability, a heap-based out-of-bounds write in the decode_lzss() function of the PAA file format plugin, allows data to be written beyond the intended memory buffer. This could lead to heap metadata corruption and potentially enable the attacker to execute arbitrary code on the affected system.

CVE-2026-15028

CVE-2026-15028 - LOW Severity Vulnerability

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.

CVE-2026-53877

Heap buffer over-read in GDALRaster

An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `django.contrib.gis.gdal.GDALRaster` over-reads its in-memory buffer when constructed from a bytes object, which can disclose adjacent memory or cause service degradation via a potential segmentation fault when the `vsi_buffer` property is accessed. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Bence Nagy for reporting this issue.
