Memory consumption errors in Apache Portable Runtime and APR Utility Library could result in Denial of Service.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/apr | * | < 1.4.8-r1 | >= 1.4.8-r1 |
| dev-libs/apr-util | * | < 1.3.10 | >= 1.3.10 |
The Apache Portable Runtime (aka APR) provides a set of APIs for creating platform-independent applications. The Apache Portable Runtime Utility Library (aka APR-Util) provides an interface to functionality such as XML parsing, string matching and database connections.
Multiple vulnerabilities have been discovered in Apache Portable Runtime and APR Utility Library. Please review the CVE identifiers referenced below for details.
A remote attacker could cause a Denial of Service condition.
There is no known workaround at this time.
All Apache Portable Runtime users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/apr-1.4.8-r1"
All users of the APR Utility Library should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/apr-util-1.3.10"
Packages which depend on these libraries may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
Multiple integer overflows in the Apache Portable Runtime and its Utility Library might allow for the remote execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/apr | * | < 1.3.8 | >= 1.3.8 |
| dev-libs/apr-util | * | < 1.3.9 | >= 1.3.9 |
The Apache Portable Runtime (aka APR) provides a set of APIs for creating platform-independent applications. The Apache Portable Runtime Utility Library (aka APR-Util) provides an interface to functionality such as XML parsing, string matching and databases connections.
Matt Lewis reported multiple Integer overflows in the apr_rmm_malloc(), apr_rmm_calloc(), and apr_rmm_realloc() functions in misc/apr_rmm.c of APR-Util and in memory/unix/apr_pools.c of APR, both occurring when aligning memory blocks.
A remote attacker could entice a user to connect to a malicious server with software that uses the APR or act as a malicious client to a server that uses the APR (such as Subversion or Apache servers), possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All Apache Portable Runtime users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/apr-1.3.8"
All APR Utility Library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/apr-util-1.3.9"
Multiple vulnerabilities in the Apache Portable Runtime Utility Library might enable remote attackers to cause a Denial of Service or disclose sensitive information.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/apr-util | * | < 1.3.7 | >= 1.3.7 |
The Apache Portable Runtime Utility Library (aka apr-util) provides an interface to functionality such as XML parsing, string matching and databases connections.
Multiple vulnerabilities have been discovered in the APR Utility Library:
A remote attacker could exploit these vulnerabilities to cause a Denial of Service (crash or memory exhaustion) via an Apache HTTP server running mod_dav or mod_dav_svn, or using several configuration files. Additionally, a remote attacker could disclose sensitive information or cause a Denial of Service by sending a specially crafted input. NOTE: Only big-endian architectures such as PPC and HPPA are affected by the latter flaw.
There is no known workaround at this time.
All Apache Portable Runtime Utility Library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/apr-util-1.3.7"
