Summary

An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap overflow in the parser for AIX log messages. The parser tries to locate a log message delimiter (in this case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. The following step in the parser is to shift left the contents of the message. To do this, it will call memmove with the right pointers to the target and destination strings, but the lenMsg will now be interpreted as a huge value, causing a heap overflow.

The parser tries to locate a log message delimiter (in this case, a space or a colon) but fails to account for strings that do not satisfy this constraint.

The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. The following step in the parser is to shift left the contents of the message. To do this, it will call memmove with the right pointers to the target and destination strings, but the lenMsg will now be interpreted as a huge value, causing a heap overflow.(CVE-2019-17042) - An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap overflow in the parser for AIX log messages.

    descriptionThis update for rsyslog fixes the following issues : Security issues fixed : CVE-2019-17041: Fixed a heap overflow in the parser for AIX log messages (bsc#1153451). CVE-2019-17042: Fixed a heap overflow in the parser for Cisco log messages (bsc#1153459). Non-security issues fixed: Handle multiline messages correctly when using the imfile module. (bsc#1015203) Fix a race condition in the shutdown sequence in wtp that was causing rsyslog not to shutdown properly. (bsc#1022804) Fixed a rsyslogd SIGABORT crash if a path does not exists (bsc#1087920). Fixed an issue where configuration templates where not consistently flushed (bsc#1084682). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.
