UBUNTU-CVE-2026-116273

MIME::Parser versions before 5.521 for Perl set no limit on the number of message parts by default, allowing memory exhaustion. The maxparts option defaulted to -1, which disables the limit, so a parser created with default settings builds an entity for every part however many a message has...

UBUNTU-CVE-2026-116135

HTTP::Body versions before 1.2301 for Perl drop mixed-case percent escapes from urlencoded form fields instead of decoding them. The decode table holds only the all-lowercase and all-uppercase spelling of each hex pair, while the escape pattern matches either case. An escape such as %aB finds no...

UBUNTU-CVE-2026-116131

HTTP::Body versions before 1.2301 for Perl allow memory and temporary file exhaustion via an unlimited number of form fields and multipart parts.

UBUNTU-CVE-2026-116133

HTTP::Body versions before 1.2301 for Perl allow CPU exhaustion via quadratic rescanning of a multipart body with a missing or malformed boundary. Before the first part, and between parts, the multipart parser searches the whole buffered body for the next boundary. On a miss it keeps everything a...

UBUNTU-CVE-2026-116531

HTTP::Body versions before 1.2301 for Perl lose track of chunk boundaries in chunked request bodies when a read ends inside a chunk. In chunked mode, used when no content length is given, add treats a chunk as complete once the buffer is as long as the chunk's declared size, but the buffer still...

UBUNTU-CVE-2026-116267

MIME::Parser versions before 5.521 for Perl allow memory exhaustion via indented error messages from a truncated, deeply nested message. Each stored parser diagnostic is indented by three spaces per nesting level. When a message nested N levels deep ends without its closing boundaries, every leve...

UBUNTU-CVE-2026-116265

MIME::Field::ParamVal versions before 5.521 for Perl do not flag an ambiguous multipart boundary written as RFC 2231 continuations.
