Ubuntu 4.10 / 5.04 : bzip2 vulnerability (USN-161-1)

USN-158-1 fixed a command injection vulnerability in the 'zgrep' utility. It was determined that the 'bzgrep' counterpart in the bzip2 package is vulnerable to the same flaw. bzgrep did not handle shell metacharacters like '|' and '&' properly when they occurred in input file names. This could be...

Ubuntu 4.10 / 5.04 : bzip2 vulnerabilities (USN-127-1)

Imran Ghory discovered a race condition in the file permission restore code of bunzip2. While a user was decompressing a file, a local attacker with write permissions in the directory of that file could replace the target file with a hard link. This would cause bzip2 to restore the file permissio...

First, a carefully constructed invalid bzip2 archive can cause bzip2 to enter an infinite loop. Second, when creating a new file, bzip2 closes the file before setting its permissions. Impac...

Debian DSA-741-1 : bzip2 - infinite loop

Chris Evans discovered that a specially crafted archive can trigger an infinite loop in bzip2, a high-quality block-sorting file compressor. During uncompression this results in an indefinitely growing output file which will finally fill up the disk. On systems that automatically decompress bzip2...
