python: CPU denial of service via inefficient IDNA decoder

A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the IDNA RFC 3490 decoder, such that a crafted unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be...

OESA-2023-1111 harfbuzz security update

HarfBuzz is a text-shaping engine. If you give HarfBuzz a font and a string containing a sequence of Unicode codepoints, HarfBuzz selects and positions the corresponding glyphs from the font, applying all of the necessary layout rules and font features. HarfBuzz then returns the string to you in...

SUSE CVE-2020-5238

The table extension in GitHub Flavored Markdown before version 0.29.0.gfm.1 takes On n time to parse certain inputs. An attacker could craft a markdown table which would take an unreasonably long time to process, causing a denial of service. This issue does not affect the upstream cmark project...

SUSE CVE-2020-7212

The encodeinvalidchars function in util/url.py in the urllib3 library 1.25.2 through 1.25.7 for Python allows a denial of service CPU consumption because of an inefficient algorithm. The percentencodings array contains all matches of percent encodings. It is not deduplicated. For a URL of length ...

SUSE CVE-2020-10735

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int"text", a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits float, decimal, int.frombytes, and int for binary bases 2, 4, 8, 16, and 32 are no...

SUSE CVE-2021-28677

An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could...
