@@ -4,6 +4,35 @@ Version 4.6.2 [v4-stable] (rgerhards), 2010-03-?? pathes (this is primarily meant as a debug aid) - added replacements for atomic instructions on systems that do not support them. [backport of Stefen Sledz' patch for v5) +- bugfix(temporary): message-induced off-by-one error (potential segfault) + Some types of malformed messages could trigger an off-by-one error + (for example, \0 or \n as the last character, and generally control + character escaption is questionable). This is due to not strictly + following a the \0 or string counted string paradigm (during the last + optimization on the cstring class). As a temporary fix, we have + introduced a proper recalculation of the size. However, a final + patch is expected in the future. See bug tracker for further details + and when the final patch will be available: + http://bugzilla.adiscon.com/show_bug.cgi?id=184 + Note that the current patch is considered sufficient to solve the + situation, but it requires a bit more runtime than desirable. +- bugfix: potential segfault in dynafile cache + This bug was triggered by an open failure. The the cache was full and + a new entry needed to be placed inside it, a victim for eviction was + selected. That victim was freed, then the open of the new file tried. If + the open failed, the victim entry was still freed, and the function + exited. However, on next invocation and cache search, the victim entry + was used as if it were populated, most probably resulting in a segfault. +- bugfix: race condition during directory creation + If multiple files try to create a directory at (almost) the same time, + some of them may fail. This is a data race and also exists with other + processes that may create the same directory. We do now check for this + condition and gracefully handle it. +- bugfix: potential re-use of free()ed file stream object in omfile + when dynaCache is enabled, the cache is full, a new entry needs to + be allocated, thus the LRU discarded, then a new entry is opend and that + fails. In that case, it looks like the discarded stream may be reused + improperly (based on code analysis, test case and confirmation pending) - added new property replacer option "date-rfc3164-buggyday" primarily to ease migration from syslog-ng. See property replacer doc for details. [backport from 5.5.3 because urgently needed by some] |
