Internet Bug Bounty: rsync hash collisions may allow an attacker to corrupt or modify files

The rsync algorithm synchronizes remote files in 3 steps: - The receiver divides the basis file into 700-byte blocks, performing two checksums on each block a rolling checksum based on Addler32 and an md5 sum - The sender then scans it's version of the file byte-by-byte looking for matches agains...

openSUSE Security Update : tinyproxy (openSUSE-SU-2013:1201-1)

Tinyproxy allowed remote attackers to cause a denial of service CPU and memory consumption via 1 a large number of headers or 2 a large number of forged headers that trigger hash collisions predictably. bucket. This update fixes this by limiting headers and improving the hash keying. %NASLMINLEVE...

CVE-2013-7040

CVE-2013-7040 affects Python 2.7 before 3.4. The issue stems from Python’s hash randomization using only the last eight bits of the prefix, which can enable context-dependent attackers to trigger hash collisions and cause a denial of service (CPU consumption) in applications that rely on hash tab...
