CVE-2025-55197 (GCVE-0-2025-55197)

Vulnerability from cvelistv5 – Published: 2025-08-13 23:03 – Updated: 2025-08-14 14:50

Title

pypdf's Manipulated FlateDecode streams can exhaust RAM

Summary

pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including the fixed code from pypdf.filters.decompress into the existing filters file.

Severity

CVE-2026-27024 (GCVE-0-2026-27024)

Vulnerability from cvelistv5 – Published: 2026-02-20 21:10 – Updated: 2026-02-24 18:34

Title

pypdf has a possible infinite loop when processing TreeObject

Summary

pypdf is a free and open-source pure-python PDF library. Prior to 6.7.1, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires accessing the children of a TreeObject, for example as part of outlines. This vulnerability is fixed in 6.7.1.

Severity

6.9 (Medium)

CVE-2026-27025 (GCVE-0-2026-27025)

Vulnerability from cvelistv5 – Published: 2026-02-20 21:11 – Updated: 2026-02-24 18:40

Title

pypdf has possible long runtimes/large memory usage for large /ToUnicode streams

Summary

pypdf is a free and open-source pure-python PDF library. Prior to 6.7.1, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes and large memory consumption. This requires parsing the /ToUnicode entry of a font with unusually large values, for example during text extraction. This vulnerability is fixed in 6.7.1.

Severity

6.9 (Medium)

CVE-2026-27026 (GCVE-0-2026-27026)

Vulnerability from cvelistv5 – Published: 2026-02-20 21:12 – Updated: 2026-02-24 18:47

Title

pypdf possibly has long runtimes for malformed FlateDecode streams

Summary

pypdf is a free and open-source pure-python PDF library. Prior to 6.7.1, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires a malformed /FlateDecode stream, where the byte-by-byte decompression is used. This vulnerability is fixed in 6.7.1.

Severity

6.9 (Medium)
