Vulnerability from csaf_microsoft - Published: 2016-11-02 00:00 - Updated: 2024-06-30 07:00

Summary

A null pointer dereference bug affects the 16.02 and many old versions of p7zip. A lack of null pointer check for the variable folders.PackPositions in function CInArchive::ReadAndDecodePackedStreams in CPP/7zip/Archive/7z/7zIn.cpp as used in the 7z.so library and in 7z applications will cause a crash and a denial of service when decoding malformed 7z files.

OESA-2021-1294 (CVE-2017-17969)

Vulnerability from osv_openeuler – Published: 2021-07-31 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

p7zip security update

Details

7za for Linux system to archive file as 7z file format

Security Fix(es):

Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.(CVE-2017-17969)

Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, allows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.(CVE-2018-5996)

Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.(CVE-2018-10115)

Severity

7.8 (High)
