There are 3 open security issues in trixie.
3 issues left for the package maintainer to handle:
- CVE-2025-66382:
(postponed; to be fixed through a stable update)
In libexpat through 2.7.3, a crafted file with an approximate size of 2 MiB can lead to dozens of seconds of processing time.
- CVE-2026-113351:
(needs triaging)
libexpat 2.7.2 through 2.9.0 contains a denial of service vulnerability because XML_ParserReset zeroes the direct byte count but never offsets tracked heap allocations. Attackers can submit a large XML document so later documents on the same reset parser fail with XML_ERROR_NO_MEMORY until it is recreated.
- CVE-2026-115506:
(needs triaging)
libexpat through 2.9.0 contains a denial of service vulnerability because billion laughs protection in accountingDiffTolerated() in xmlparse.c detects entity amplification too late. Attackers can supply a moderately sized XML document with a large DTD and nested entity expansions to consume tens of seconds of CPU per parse.
You can find information about how to handle these issues in the security team's documentation.
